If your Joomla 3.10 site shows warnings about extensions or plugins when preparing to upgrade to Joomla 4, you are not alone. These warnings are often a sign that third‑party code needs attention before the core upgrade. Rushing the process can break your site; this guide gives a safety‑first, stepwise plan you can follow even without deep coding skills.
What you'll get: a practical inventory and compatibility checklist, instructions to create a test (staging) copy, a staged upgrade workflow, options for unsupported extensions, rollback guidance, and a short FAQ. Verify key technical details against official Joomla documentation before applying changes to production.
Quick overview: What changes between Joomla 3.10 and Joomla 4 (and why extensions matter)
Joomla 4 introduced modernised APIs, stricter PHP practices and frontend/template changes. These are positive improvements, but third‑party extensions or templates that were written for Joomla 3.x may use deprecated APIs, non‑namespaced classes, or older PHP features. When the core or PHP version changes, incompatible code can trigger warnings or fatal errors.
Beginner-friendly explanation of core changes
At a high level, Joomla 4 focuses on cleaner APIs, namespacing, and better error handling. The frontend also uses an updated approach to assets and layout conventions. In plain terms: older extensions may still run on 3.10 but need updates to work correctly under Joomla 4 and newer PHP versions.
Minimum server and PHP requirements (verify current official Joomla docs)
Joomla 4 requires a higher PHP baseline than many legacy Joomla 3 sites. Do not change the PHP version on production before testing on staging. Exact minimum and recommended PHP versions can change over time — verify the current requirements against the official Joomla documentation before making production changes.
Practical example
Example: an image gallery plugin that uses deprecated Joomla 3 API calls may appear to work on Joomla 3.10 under PHP 7.4 but fail with fatal errors when Joomla 4 is installed and PHP is upgraded. Testing the plugin on a staging copy under the target PHP version will reveal these issues before they affect live users.
Warnings
Changing PHP on a live site without backups and staging tests can cause immediate downtime.
Do not assume a site that loads under an old PHP version will behave the same after upgrading core or PHP.
Pre-upgrade checklist — what to do before touching the live site
This checklist helps you prepare the environment, reduce surprises, and set realistic expectations for testing and downtime.
Essential pre-upgrade checklist (prioritised)
Inventory all extensions and the active template (see next section for details).
Create full backups of files and database and verify you can restore them.
Create a staging copy that mirrors the live site as closely as possible.
Plan a rollback procedure and define acceptance criteria for the upgraded site.
Schedule a maintenance window and notify stakeholders if you expect downtime.
Backup checklist (files + DB) and recommended tools
Use a proven Joomla backup solution or your hosting snapshot tool. Ensure backups include the full file tree and a complete database dump.
Store backups offsite (download to local storage or cloud) and verify restores to a staging server.
Test the restore process at least once before the upgrade attempt. A backup that cannot be restored is not useful.
How to create a staging site for Joomla
Options: subdomain (a protected staging subdomain), subfolder with password protection, or a local environment.
Mirror PHP version and PHP extensions on staging where possible. If you cannot mirror everything, document differences.
Block search engines and restrict access (HTTP auth or IP restriction) to prevent public exposure.
Plan test sign-off and downtime windows
Define what “working” means before you upgrade. Example acceptance criteria:
Homepage and top 10 pages load without errors.
Admin login and content editing work.
Critical extensions (e.g., forms, payments, membership) function as expected.
Warnings
Never perform major upgrades on live without a verified staging test.
Backups must include both files and database; a DB-only backup is not enough to restore the site fully.
Inventory your site: list core vs third-party extensions and templates
A clear inventory helps you prioritise which items need attention and communicates requirements if you hire a developer.
What to record for each extension
Name and type (component, module, plugin, library, template)
Version number
Vendor or source
Last update date
Whether there is known Joomla 4 support
How to export a full extension list from Extensions Manager
In Admin: Extensions → Manage → Manage. Use filters to view installed items. If your Joomla admin has no export button, you can:
Use an admin tool/extension that exports to CSV (if available and compatible).
Capture screenshots or copy the list into a spreadsheet manually.
Identify templates and template overrides
Locate the active template and inspect the template's html override folders for custom file changes. Custom overrides are a common cause of layout and module position breakages after upgrade.
Warnings
Do not delete extensions during inventory—record details first.
Custom code or overrides may not have vendor support and need special attention.
Compatibility checks: how to verify extensions, templates and PHP compatibility
Use vendor pages, changelogs and staged tests to confirm compatibility. Automated compatibility flags are useful but never replace a staging test.
Prioritise extensions by criticality
Focus first on payment gateways, authentication, membership, forms, backups, and security extensions. These have the highest business impact if they fail.
Using the Joomla Update component vs CLI upgrades (pros and cons)
GUI update: easier for beginners and smaller sites; follow prompts in the administrator update interface.
CLI update: better control and automation for larger sites; CLI commands and usage must be verified before use and require shell access.
Recommendation: test the GUI flow on staging first. For larger sites, test CLI on staging and confirm commands with official documentation before production use.
How to detect template issues and common fixes
Look for missing module positions, layout breakage, CSS or JS conflicts, and deprecated Bootstrap classes.
Fixes: update the template if a Joomla 4-compatible version exists; adjust overrides; or switch to a compatible template.
Contacting extension vendors and checking changelogs
Check vendor pages and changelogs for Joomla 4 compatibility notes. When contacting vendors, ask if a Joomla 4 release is available and timelines for any planned updates.
Warnings
Do not assume 'no recent updates' means 'works'—test in staging under the target PHP and Joomla versions.
Compatibility flags in directories are helpful but not definitive; always validate in a staging environment.
Create backups and a staging (test) site
Backups and a protected staging environment are essential. The restore must be tested before you rely on it for rollback.
Restoring a backup to a staging server step-by-step
Create a full site archive (files + DB) on production.
Create a new database and user on staging and import the DB dump.
Upload files to staging, update configuration.php with staging DB credentials and URLs.
Clear caches, run any required database fixes, and test admin and frontend logins.
Switching PHP version safely on staging
Use your host control panel (e.g., PHP selector) or CLI to change PHP on staging first.
Enable detailed error reporting on staging (but never on production) to capture incompatibilities.
Test all critical workflows after switching PHP and before attempting a core upgrade.
Warnings
Be careful with scheduled tasks, email sending, or integration hooks when restoring to staging—disable cron jobs or mail sending to avoid accidental deliveries.
Update configuration.php and any hardcoded absolute URLs after restore to avoid broken links or sending data to live services.
Practical upgrade path: step-by-step on a staging site
Follow this sequence on staging. Only after the staging site passes your acceptance checklist should you plan the production upgrade.
Ensure staging is an up-to-date copy of production.
Disable caching and optimization plugins to simplify debugging.
Enable Joomla debug and check error logging levels (on staging only).
Step 2: Update compatible extensions first
Apply updates to extensions that explicitly list Joomla 4 compatibility.
Update in small batches and retest key site functions after each batch.
Step 3: Perform Joomla core upgrade and post-upgrade database tasks
Run the core upgrade using the Joomla Update component on staging or CLI if you have a tested process.
After the upgrade, go to Extensions → Manage → Database (or similar) to apply any required fixes, then clear caches and check logs.
Step 4: Replace or patch unsupported extensions
If an extension fails after the core upgrade, seek an updated release or a replacement.
For data-bearing extensions, export data first and test import into the replacement extension on staging.
Practical example
Switch staging to the target PHP version, update three extensions that already support Joomla 4, run the core upgrade, and then replace a legacy plugin with a modern alternative while preserving its data via export/import—testing each step as you go.
Warnings
If the core upgrade is interrupted (timeout, process killed), you may get a partial upgrade. Ensure staging has higher timeout limits for long operations.
Watch for fatal PHP errors during upgrade and resolve them before attempting the production upgrade.
Handling unsupported or abandoned extensions: update, replace or remove
When a vendor is unresponsive or an extension is abandoned, weigh the importance of the feature against migration effort and security risk.
Decision checklist
Is the extension critical to core business processes?
Are there mature replacements with migration paths?
Can a developer patch or port the extension affordably?
Is there sensitive or hard‑to‑migrate data tied to the extension?
Selection checklist for replacement extensions
Active development and recent updates
Explicit Joomla 4 compatibility
Good documentation and available support
Clear migration guides or import tools
How to hire a developer for migration or patching
Provide a clear brief: inventory list, staging access, list of critical user flows, required acceptance tests and a rollback plan. Ask for Joomla 3→4 upgrade references and a written testing plan.
Removing an extension safely
Export all data related to the extension (contacts, records, settings).
Disable the extension and test site functionality.
If no issues, remove the extension and keep an archived copy of its files and DB export in case rollback is needed.
Warnings
Removing or replacing an extension can lead to data loss if exports or migrations are not performed correctly.
Do not patch core or vendor code on production without version control and staging validation.
Testing and troubleshooting after the upgrade
Use a prioritised test plan and capture errors with browser dev tools and server logs to identify root causes.
Testing checklist: frontend, backend, components and user flows
Homepage and representative content pages
Admin login, content creation and editing
Forms, checkout/payment flows, membership login and renewals
Search, SEO redirects, scheduled tasks and integrations (APIs, webhooks)
ACL and user role checks
Using browser dev tools and PHP/log files
Open the browser console to capture JS errors and network failures.
Check Joomla and PHP error logs for warnings or fatal errors. Enable debug on staging for detailed traces.
Where an error points to a specific extension file, note the vendor and version for remediation.
Common post-upgrade fixes
Update templates or adjust overrides for changed module positions.
Apply database fixes from the Joomla Extensions → Manage → Database tool.
Reinstall or update extensions that did not complete during the core upgrade.
Warnings
Do not enable Joomla debug mode on production; it can expose sensitive information.
Log files can grow quickly during intense debugging; monitor disk space.
Rollback and recovery plan
Despite careful testing, you may need to revert a production upgrade. A clear rollback plan minimises downtime and data loss.
Restoring a backup to production safely
Place the site in maintenance mode and take a final snapshot of current state.
Restore files and DB from the pre-upgrade verified backup.
Clear caches, reconfigure configuration.php if needed, and run basic smoke tests (login, homepage, critical flow).
Notify stakeholders once the site is back online.
Partial rollback strategies to preserve data
If new transactions occurred after the failed upgrade (orders, signups), export these records before restoring the old database so they can be re‑imported afterwards. Use selective table exports and document mapping carefully.
Warnings
Rolling back the database will revert any new content or transactions — coordinate with stakeholders and export recent data first.
Always test your restore process on staging before relying on it for rollback.
When to hire professional help
Large or complex sites, custom integrations, heavy e-commerce, or sites with bespoke extensions are usually better handled by experienced Joomla developers or agencies.
How to scope an upgrade project for a freelancer or agency
Provide a full inventory, describe critical workflows and acceptance criteria, and grant access to staging and live environments.
Ask for a written plan: backup strategy, testing checklist, expected timeline and rollback steps.
Red flags when hiring
Vendors who don't ask about backups or testing procedures.
Vendors who insist on performing risky changes on live without a staged plan or verified backups.
Warnings
Always require work to be done on staging first; avoid vendors who insist on only live changes.
Request references and examples of Joomla 3→4 upgrades they have completed.
FAQ
Will my site 'blow up' if I try an automatic upgrade?
An automatic upgrade can succeed for well‑maintained sites where extensions and templates are already compatible. The risk increases when many third‑party items show warnings or are unmaintained. Use staging and backups to avoid surprises. Verify the Joomla Update component's behavior in the official docs before relying solely on it.
How do I know which extensions are safe to keep?
Check vendor changelogs, Joomla Extensions Directory compatibility indicators, and recent update dates. Most importantly, test each extension on a staging copy under the target Joomla and PHP versions.
Do I need to change my PHP version before upgrading Joomla?
Verify Joomla 4's PHP requirements first. Best practice: test the PHP version change on staging and resolve any extension incompatibilities before upgrading the core on production.
What if an extension is abandoned and there is no upgrade path?
Options include replacing it with a maintained alternative, hiring a developer to port or patch it, or removing and re-creating functionality. Always export and preserve data before removing such extensions.
How can I roll back if the upgrade fails?
You need verified pre-upgrade backups (files + DB). Put the site in maintenance mode, restore the backup, and test critical flows. If new data exists after the failed upgrade, export it before restoring so you can re-import or merge it later.
Is the Joomla Update component sufficient for the 3.10 → 4 upgrade?
The Joomla Update component can perform in‑place updates in many cases, but behaviour varies by site complexity and installed extensions. Confirm the recommended workflow in the official Joomla documentation and test the process on staging first.
Can I keep my custom template?
Only if the template and its overrides are compatible with Joomla 4 or can be updated. Test visual output and module positions on staging; update or switch to a Joomla 4 compatible template if problems are found.
Conclusion
Upgrading from Joomla 3.10 to Joomla 4 when your site shows extension or template warnings is a manageable project if you follow a cautious process: inventory your site, create verified backups, build a protected staging copy, check compatibility and update or replace problematic extensions, run the core upgrade on staging, test thoroughly, and only then upgrade production. When in doubt—especially for complex or business‑critical sites—hire experienced Joomla help and always verify technical steps against the official Joomla documentation.
Next steps: create your inventory, schedule a staging restore, and run initial compatibility tests. Verify the technical requirements and update paths mentioned here against the official Joomla documentation before performing production changes.
Administering users is one of the most repetitive tasks on many Joomla sites. Opening individual profiles, applying the same change dozens of times, running ad-hoc exports and double-checking permissions can eat hours each week. This guide gives beginner-friendly, practical workflows to save time while keeping your site safe: what the Joomla core can do, how to work safely with batches and exports, how to evaluate extensions or build a custom tool, and checklists you can apply immediately.
Quick overview: Why default Joomla user management can feel slow
Many administrators describe Joomla's built-in user administration as slow because daily tasks often require opening and saving single user forms repeatedly, applying filters that are too basic for complex selection criteria, and exporting data manually. Small tasks repeated many times become a large time sink.
Examples of repetitive tasks that slow admins down
Moving a cohort of users to a different group (for promotions or subscription changes).
Batch blocking or unblocking accounts after an incident or cleanup.
Periodic exports for audits, newsletters or CRM imports.
Correcting custom profile fields across many users (e.g., adding missing metadata).
Practical example: if editing a single profile takes ~90 seconds (open, change, save, confirm), doing the same for 100 users can easily take 2–3 hours. A safe batch workflow can reduce this to a small fraction of the time.
Warning:
Do not run raw SQL updates on a live production database unless you are an experienced developer. Direct DB changes can corrupt ACL relationships or leave inconsistent states.
What the Joomla core User Manager can (and can't) do
The Joomla core User Manager provides list, filter and some batch actions. It is a good first stop for many routine tasks, but it has limits. Use core features first and escalate to extensions only when necessary.
Core: bulk operations, filters and batch actions (what to try first)
Open the User Manager list view and try the available filters (group, status, search). Practice selecting a small set of users and applying a batch action.
Export or copy the selected users' basic details to keep a pre-change record (if your site or extensions provide export).
Perform a test change on 5–10 users and verify results on the site and front end.
What core does not provide (and why extensions help)
Core limitations commonly reported include lack of inline grid editing, limited multi-field filtering, and limited export options. Extensions or custom tools address these gaps by offering inline editing, advanced saving workflows and richer export formats.
Technical caution:
Core batch actions may have side effects on ACL or related data. Always test batch behaviour in a staging environment before running large operations in production.
Verify:
Check the official Joomla documentation for the stable release you run to confirm the exact User Manager capabilities, batch action names and menu paths before following interface-specific instructions.
Safe, practical workflows to speed up common tasks
Speed gains come from replacing repeated manual edits with small, verifiable batch operations. Follow a checklist-based workflow to reduce risk.
Pre-change checklist (use for every bulk task)
Define the goal and exact criteria for affected users.
Export or snapshot the affected users (pre-change record).
Take a recent site/database backup or create a restore point.
Run the change on a small test group in staging or a low-risk subset.
Verify results (front end and back end) and check logs.
Perform the full batch in production, monitoring server resources.
Document the change for audit and future rollback.
Use-case: update user group for many users (step-by-step)
Define criteria. Example: "trial" users older than 14 days need to be promoted to "Registered".
Filter users to identify matches and export their id, username, email and current groups as a CSV for a record.
Create a backup or database snapshot before changes.
Test: apply the group change to 5–10 accounts and verify their front-end permissions.
Run the full batch (or split into smaller batches) and re-check a random sample of accounts.
Log who ran the job, when, and what was changed.
Use-case: filter by multiple fields and export CSV
If your core UI cannot combine all needed filters, consider a trusted extension or export the broader set and filter offline. When exporting:
Export only necessary fields to reduce exposure of PII.
Secure exported files (password-protected ZIP or encrypted storage).
Delete or archive the file as soon as it is no longer needed.
Permissions & ACL: who should be allowed to run bulk jobs
Assign bulk-change capabilities only to trusted administrator accounts. Use least-privilege principles and create a dedicated maintenance role if needed. Keep records of who performed bulk actions.
Warnings:
Large batches can time out on low-resource hosting; break jobs into smaller groups.
Group and ACL changes may change access rights unexpectedly. Test in staging first.
Verify:
Confirm whether your Joomla installation logs admin batch actions automatically; if not, ensure you record actions manually or via an auditing extension.
Third-party extensions and tools that add grid/inline editing, advanced filtering and exports
When core features are not enough, an extension can provide inline editing, richer filters, and export formats. Choose carefully.
Check Joomla version compatibility and supported PHP versions.
Prefer extensions with recent updates, active support and a changelog showing security fixes.
Confirm the extension respects Joomla ACL and custom fields.
Review how the extension handles exports and whether it includes sensitive fields by default.
Automating exports vs manual exports: pros and cons
Automated scheduled exports save time but increase potential exposure. Use secure transport (SFTP, encrypted storage) and restrict who can manage schedules. For sensitive sites, manual exports reduce automation risk but require process discipline.
Technical warnings:
Avoid extensions that expose plaintext passwords, session tokens or that require excessive permissions.
Always test extensions in staging before installing on production.
Verify:
Before publishing any extension recommendations, confirm the names, capabilities and compatibility of extensions via the official Joomla Extensions Directory and vendor pages.
How to perform bulk updates safely (step-by-step)
Follow these concrete steps for any bulk user update to reduce the chance of errors and provide straightforward rollback options.
Seven-step bulk update procedure
Define the exact change and the selection criteria.
Take a full site backup or at least a database snapshot.
Create a staging copy or test subset with masked PII.
Run the batch on a small sample and verify behavior and ACL effects.
Confirm monitoring and logs are available during production run.
Execute the full batch, breaking into smaller groups if needed.
Perform post-change verification and document the operation.
Mirroring a subset of production to staging helps you test ACL and front-end effects. Mask or anonymize PII on staging if you cannot secure it to avoid unnecessary exposure.
Undo strategies: backups, database snapshots and transaction logs
Restore from a full backup or snapshot when the change is destructive and broad.
If you exported a pre-change CSV, use it to reverse changes via a trusted import tool or extension.
Extensions that support transactions or an undo log are preferable; verify this feature on staging.
Warnings:
Partial rollbacks risk inconsistent states (e.g., group changed but related content still references old permissions).
Backups often contain PII — store them securely and delete when they are no longer needed.
Exporting user data: formats, tools and privacy considerations
Exporting user data is a common administrative need, but it carries privacy and compliance responsibilities. Use the principle of minimal export: only extract fields you truly need.
Common formats and when to use them
CSV: universal and simple for lists, suitable for spreadsheets and quick imports.
Excel (XLSX): useful when formatting or multiple sheets are required.
JSON: preferred for programmatic consumption or API integrations.
Data protection checklist (GDPR, PII handling) before exporting
Confirm a legal basis for processing and exporting user data (consult legal counsel if unsure).
Export only necessary fields; avoid password hashes, reset tokens and session data.
Password-protect and encrypt exported files; use secure transfer channels (SFTP/HTTPS).
Log who exported data and why, and set deletion or retention deadlines.
Warnings:
Never include password hashes, reset tokens, or session data in exports.
Be cautious about custom fields — they can contain address, phone and other sensitive PII.
Verify:
Confirm whether your Joomla core or installed extensions expose direct export functionality and which fields are included by default. Cross-check against official docs before exporting.
If you want a custom tool: checklist for features, security and UX
Teams building a custom user-management tool should define functional and non-functional requirements up front. Below are recommended items to include in acceptance criteria.
Essential features checklist
Inline edit with per-row save or a save-all option.
Multi-select and multi-field batch actions with dry-run (preview) mode.
Audit log that records who changed what and when.
Export controls that let admins select fields and enforce PII minimization.
Pagination and performance safeguards for large user tables.
Security checklist for custom tools
Respect Joomla ACL — never bypass Joomla permission checks.
Validate and sanitize all inputs; use prepared statements or Joomla’s ORM.
Never expose passwords in plaintext or in exports.
Store exported files outside webroot and protect them with access controls.
UX checklist
Provide undo or dry-run options for destructive actions.
Show progress and estimated time for long jobs.
Offer saved filters and a preview of affected rows before committing changes.
Technical warnings:
Custom tools must not write directly to core user tables without going through Joomla APIs or respecting relationships to user_profile and ACL tables. Test all writes in staging.
Verify:
Check Joomla developer documentation for the recommended extension APIs and plugin events you should use for safe user updates.
Testing, backups and rollback strategies
Robust testing and rollback plans are essential. Below are practical techniques for administrators with limited development resources.
Preparing staging and test data
Copy production to staging and mask or anonymize PII where possible.
Test the exact batch operation on staging and verify front-end behavior for affected roles.
Undo strategies: practical steps
If a mistake occurs, restore a database snapshot taken immediately before the change.
If you exported a pre-change CSV, use a trusted import process to revert changed fields selectively.
Maintain incremental change logs so targeted fixes are possible without full restores.
Warnings:
Restores may overwrite other recent changes; coordinate restores with stakeholders.
Backups containing PII require secure storage and limited access.
Verify:
Check your hosting provider's snapshot and restore capabilities and the recommended backup tools for Joomla sites before relying on a given method.
When not to use bulk edits: common pitfalls
Bulk edits are powerful but inappropriate in some situations. Prefer manual checks or staged approaches when precision matters.
When to avoid bulk edits
Changes that require per-user manual verification (sensitive or personalized profile corrections).
Any bulk change that touches authentication mechanisms (passwords, authentication plugins or session tables).
Large-scale changes on very large user tables during peak hours (risk of timeouts and lock contention).
Performance considerations for very large user tables
Break updates into batches (for example, 500 users per batch), run during off-peak windows, and consider DB optimization or DBA assistance if the site handles tens or hundreds of thousands of users.
Example alternative:
Instead of bulk resetting passwords for thousands of users, send a password-reset email workflow that respects consent and avoids exposing credentials.
Verify:
Before making changes touching authentication fields, confirm how Joomla core and any installed extensions handle sessions and password fields.
Summary and next steps
Combining Joomla core features, safe batch procedures and well-chosen extensions will let you manage users much faster without increasing risk. Always test in staging, make backups, and prefer minimal-data exports.
Suggested next actions
Identify one repetitive user task you perform now (e.g., group changes). Create a short checklist for that task following the seven-step procedure above.
Test that task in a staging environment and document the exact steps and expected outcomes.
If core features are insufficient, evaluate one extension using the extension checklist in this article.
Can I bulk edit users in Joomla without installing an extension?
Yes — Joomla core typically includes batch actions in the User Manager for common changes such as changing groups or blocking/unblocking users. Core capabilities vary by Joomla version, so check your installation and test in staging first.
Is it safe to export user lists (CSV/Excel)?
Exporting user data is possible but has privacy risks. Export only the fields you need, secure exported files (encryption/password-protect), limit retention, and log the export. Consult legal guidance for GDPR or similar regulations relevant to your jurisdiction.
How do I undo a mistaken bulk change?
The safest undo is restoring a recent backup or database snapshot. If you exported a pre-change CSV, you can use it to reverse changes selectively. Some extensions provide transaction/undo features — test those on staging before relying on them.
What permissions do I need to run bulk user updates?
Bulk updates should be restricted to trusted admin roles with user management privileges. Exact ACL permission names can vary between Joomla versions — verify the relevant permissions in your Joomla installation and apply least-privilege principles.
Which extensions add inline editing or CSV export for users?
There are extensions that provide inline editing and export features. Choose extensions that are actively maintained, clearly document compatibility with your Joomla version, and show transparent data handling policies. Verify specific extension capabilities on the Joomla Extensions Directory and vendor sites before installing.
How should I handle very large user tables?
Avoid very large single batches. Use phased updates, split into smaller batches (e.g., groups of 500), run during low-traffic windows, and consider consulting a DBA if operations remain slow even after batching.
Conclusion
Speeding up Joomla user administration is achievable with cautious use of core capabilities, sensible workflows and well-evaluated extensions or custom tools. The key priorities are testability, minimal exposure of PII, and reliable rollback options. Use the checklists in this article to standardize your approach and reduce the risk of accidental damage to your site.
Before making production changes, verify UI labels, menu paths and batch capabilities against the official Joomla documentation for your installed version, and consider legal guidance for data exports.
Upgrading a live website can feel risky, especially when the original developer is unavailable and the administration interface shows warnings about extensions. This guide gives a clear, practical checklist for non-developers to move a Joomla 3.10 site to Joomla 4 with minimal risk. You will learn how to audit extensions and templates, create a staging copy, verify backups, run the upgrade safely on staging, and prepare a rollback plan in case something goes wrong.
Throughout the article we will explain concepts in beginner-friendly language and include concrete examples and checklists. If any technical detail may change over time (for example exact PHP minimums or update-channel steps), it is listed in the technical claims to verify so you can confirm against the official Joomla documentation before making production changes.
Quick answer: is an automatic upgrade safe?
Quick answer: risk summary and one-line plan
In short: an automatic upgrade can be safe, but only when the server environment, Joomla core, template and all third-party extensions are compatible with Joomla 4. For many sites—especially those with custom or abandoned extensions—the safest route is to prepare first and run the automatic upgrade on a staging site, not on production.
One-line plan: Audit → Clone to staging → Backup → Upgrade on staging → Test → Upgrade production.
Practical example
Example one-line procedure to follow now: export an extension list from Extensions > Manage, check compatibility for each extension, create a staging copy with the same PHP version, take a verified backup, run the Joomla Update on staging and test the most-used pages, and then upgrade production during a maintenance window.
Warnings
Do not run the automatic upgrade on production without a verified backup and a successful staging run.
Administrator warnings about extensions are indicators of potential problems, not guarantees. Investigate every warning before proceeding.
Joomla 4 upgrade prerequisites (system requirements and PHP)
Before attempting any migration, confirm the server environment meets Joomla 4 requirements, and that your Joomla 3.10 installation is fully updated.
Confirm Joomla 3.10 is fully updated
Make sure your Joomla 3.10 installation is updated to the latest 3.10.x release available.
Apply extension updates that are explicitly for Joomla 3.10 before migrating.
Check PHP, database and server compatibility
Joomla 4 requires a newer PHP version and certain database versions and PHP extensions. To check your environment:
Open System > System Information in the Joomla administrator to view current PHP, MySQL/MariaDB, and loaded PHP extensions.
Or place a simple phpinfo() file on a staging server to inspect PHP settings (only on staging; remove it afterwards).
Verify required PHP extensions such as mbstring, json, xml, zip, and others are present.
Warning: changing the server PHP version on production without testing can break other sites hosted on the same account. Always replicate the environment in staging first.
Verify exact minimum PHP and database versions and required PHP extensions against the official Joomla documentation before making production changes.
Pre-upgrade checklist — what to do before you touch the live site
Do these preparatory steps before touching production. This section provides a copy-paste checklist you can follow.
Ready-to-use pre-upgrade checklist
Take a full site backup (files and database). Do not skip this.
Export or record a list of installed extensions (components, modules, plugins, templates, libraries) and their versions.
Make sure Joomla 3.10 core is updated to the latest 3.10.x release.
Update extensions that clearly state support for the latest Joomla 3.10 release.
Create a staging copy that mirrors production (files, DB and PHP version).
Disable caches, put site(s) into maintenance mode if your backup or cloning method requires it.
Backup verification and safety steps
Always test-restore a backup to a staging or local environment to confirm it can be restored.
Keep at least one off-site copy of backups and several restore points if possible.
Warning: never assume a backup is usable. Test the restore before relying on it for rollback.
Audit installed extensions, plugins and templates
Third-party extensions and templates are the most common causes of upgrade problems. A systematic audit reduces surprises.
List installed extensions and check vendor support
From Extensions > Manage, export or copy the extension list. If your admin lacks an export function, copy the list into a spreadsheet manually.
How to find extension compatibility info (developer site, JED)
Check the Joomla Extensions Directory (JED), extension vendor websites, GitHub repositories and changelogs for Joomla 4 compatibility notes. If the vendor mentions an upcoming Joomla 4 update, note the planned release date and any migration instructions.
Disable non-essential extensions for testing
On your staging site, temporarily disable optional plugins and modules to narrow down problems. Always record what you change so you can revert after testing.
Practical example audit workflow
Example spreadsheet rows may look like:
"Akeeba Backup — Component — 9.5.0 — Vendor X — OK — No action"
"Custom contact component — Component — 1.2.3 — Unknown — Abandoned — Replace or hire developer"
Warning: do not ignore extensions marked as abandoned; they commonly block upgrades. Even extensions that claim compatibility may still require testing on staging.
Handling custom or abandoned extensions
If an extension appears abandoned or is custom-built, you have several options. The correct choice depends on how critical the extension is to site functionality.
Options for abandoned/custom components (update, replace, disable)
Contact the vendor or developer to ask about Joomla 4 support.
Search for maintained forks or replacements on JED or GitHub.
If no update exists, consider replacing the extension with a maintained alternative and plan data migration if needed.
As a last resort, hire a developer to port the extension to Joomla 4.
Sample decision flow for abandoned custom extensions
Contact vendor/support.
If vendor unavailable, search for forks or alternatives.
If a compatible replacement exists, plan migration and test data mapping on staging.
If no replacement, isolate the extension on staging and test site functionality without it; if critical, hire a developer to port it.
Practical example: if a custom contact component is only used on one form, replacing it with a modern contact extension and mapping stored messages may be faster than porting the old code.
Warning: directly editing extension files on a live site can create maintenance and security issues. If you must modify code, ensure you have version control and backups.
Create a staging copy and test the upgrade
Staging is the place to find and fix problems safely. A valid staging environment mirrors production for PHP, database, and configuration.
How to clone your site: manual vs backup tool vs host staging
Manual clone: copy files via FTP/SFTP, export the production database and import into a staging database, and update configuration.php and site URLs.
Backup tool restore: create a full backup on production (files + DB) and restore to a staging subdomain using the same tool. Popular backup tools exist for Joomla; verify their compatibility with restores to staging.
Host-managed staging: many hosts offer one-click staging in their control panels. Confirm the staging site uses the same PHP and database versions or allows you to match them.
How to use backups to restore (example tools)
Akeeba Backup is commonly used for Joomla sites to create full-site archives and restore them on staging. If you use a backup tool, follow its restore instructions and verify the site functions on staging.
Practical example
Example steps using a backup tool: run backup on production, download the archive, upload and extract on staging, import the installer script if required, and run the restore. After restoring, verify site URL and database settings and block search engines from indexing the staging site.
Warning: if staging does not match production PHP or DB versions, issues may be hidden or new problems introduced. Keep staging as close as possible to production.
Backup and rollback strategy
A clear rollback plan gives you confidence to upgrade. Follow a documented backup and restore process and test it on staging.
How to use backups to restore (example tools)
Example workflow with a backup tool:
Create a full backup on production immediately before the planned upgrade.
Download and store the archive off-site (local drive or cloud storage).
Test the archive by restoring it to a staging server.
Rollback checklist
Confirm backup integrity and archive location.
Put the site in maintenance mode to prevent new content during restore.
Restore files and database from the backup archive.
Clear caches and verify front-end and admin functionality.
Remove maintenance mode once verified.
Warning: restoring a backup will revert any content changes made after the backup. For high-traffic or content-updated sites, schedule a content freeze window during the upgrade.
Step-by-step upgrade on staging (then production)
Run the upgrade first on staging and only repeat it on production when staging passes all checks.
Step-by-step: perform the upgrade in the Joomla Update component
On staging, verify that Joomla 3.10 is fully updated and that all pre-upgrade checks are complete.
Open Components > Joomla Update (or Extensions > Update depending on your admin layout).
Switch update channels if required and choose the Joomla 4 upgrade option according to official guidance. Verify the exact steps against the official Joomla documentation before proceeding.
Run the update and monitor progress. Allow time for database migrations and post-update scripts to execute.
After the update completes, clear Joomla caches and browser caches, then inspect the site for errors.
Verifying frontend and backend after upgrade
Log into the administrator and check Extensions > Manage for any disabled or broken extensions.
Visit critical front-end pages, submit forms, and test user login and any e-commerce flows if present.
Inspect PHP error logs and Joomla logs for warnings or fatal errors.
Warning: long-running updates may hit PHP execution limits. If the update fails due to timeouts, do not retry on production—restore the backup and investigate on staging. Consider running command-line updates if recommended by Joomla docs and your host supports it.
Post-upgrade checks and common fixes
After a successful upgrade, perform a focused set of checks to catch common issues quickly.
Verifying frontend and backend after upgrade
Check the homepage and top-level navigation.
Open category listings, articles, and key components (contact forms, events, shop pages).
Login to the administrator and visit extension management pages for each third-party extension.
Common post-upgrade issues (template, menu, login, admin errors)
Templates may require updates to be Joomla 4 compatible; module positions or overrides can break layouts.
Third-party extensions might need updated versions or reinstallation.
Custom code or overrides may cause PHP errors; check the logs to isolate files involved.
When to roll back and how to troubleshoot logs
If a critical feature is broken and no quick fix is available, roll back using your verified backup. Collect error messages, PHP traces and relevant Joomla logs, and document the steps you took before consulting a developer.
Warning: some post-upgrade fixes (template conversions, deep extension porting) require developer skills. Avoid editing core files—use overrides or updated extensions instead.
When to get professional help
There are good moments to call in a Joomla professional. If you meet any of the following criteria, engage a developer or a trusted Joomla agency:
Critical functionality depends on custom or abandoned extensions.
The site serves revenue-critical traffic and downtime must be minimized.
Post-upgrade errors are complex PHP or database issues beyond basic debugging.
Hiring a developer: what information to provide
Prepare a clear brief to speed up troubleshooting:
Staging URL and production URL.
Joomla and PHP versions used on staging and production.
Extension list with versions and notes about abandoned/custom items.
Backups (archive ID) and error log extracts with timestamps.
Exact steps you tried and where the process failed.
When to choose a migration vs a compatibility fix
If a vendor is not maintaining an extension and no modern replacement exists, plan for a migration or a custom port. For templates, consider switching to or purchasing a Joomla 4-ready template if conversion is costly.
Warning: choose developers with proven Joomla 3-to-4 migration experience and require version control and backups before code changes.
Resources and next steps
Final recommended steps and authoritative resources to consult before performing any production upgrade.
Useful references and tools
Official Joomla documentation — check the migration and system requirements pages before upgrading.
Joomla Extensions Directory (JED) — for checking extension compatibility and vendor information.
Backup tools and hosting staging features — choose tools compatible with your workflow and verify restore procedures.
Next steps checklist
Finish the extension audit spreadsheet and classify each item.
Create a staging copy that mirrors production and set the same PHP and DB versions.
Take and verify a full backup and test restore on staging.
Run the Joomla upgrade on staging, test thoroughly, and document issues and fixes.
Schedule a production upgrade during a low-traffic window with a content freeze if needed.
FAQ
Will my site break if I attempt an automatic upgrade?
Not necessarily, but it depends on server requirements and third-party extensions. Always audit extensions, create a staging copy, and have a verified backup before attempting the upgrade on production.
How do I identify which extensions, plugins or templates are incompatible with Joomla 4?
Export the list of installed extensions and check each entry on the Joomla Extensions Directory and vendor changelogs for Joomla 4 compatibility. On staging, disable non-essential extensions to see whether the site runs without them.
What environment and PHP versions are required before upgrading?
Joomla 4 requires a newer PHP version and specific database versions and PHP extensions. Verify the exact versions and requirements on the official Joomla requirements page before changing environments.
How do I create a safe staging copy of my live site for testing?
Options include manual cloning (files + DB), restoring a backup archive to a staging subdomain using a backup tool, or using host-managed one-click staging. Ensure staging matches production PHP and database versions and block it from search engines.
Which backups and rollback steps should I take before upgrading?
Take a full backup (files + DB), verify the backup by restoring it to staging, store an off-site copy, and prepare a tested rollback checklist so you can restore production quickly if needed.
What should I do with custom or abandoned (ghosted) extensions?
Search for vendor updates or forks, consider replacement extensions, isolate or disable the extension on staging to test impact, and hire a developer to port critical custom extensions if necessary.
How do I apply the upgrade step-by-step in Joomla 3.10 and verify success?
On staging: update Joomla 3.10 to the latest 3.10.x, follow the Joomla Update component steps to move to Joomla 4 (verify the exact procedure in official docs), run the update, clear caches and test front-end and admin features. Repeat on production with backups in place when staging passes.
When should I call a developer or migrate to a new extension?
Call a developer when the site uses complex custom code, critical functionality fails after testing, or the extension is abandoned and no reliable replacement exists. Provide logs, backups and a concise brief to speed up help.
Conclusion
Upgrading from Joomla 3.10 to Joomla 4 is achievable for site owners and beginners when approached methodically: audit extensions, create a staging copy that matches production, verify backups with a test restore, run the upgrade on staging, and only proceed to production once tests pass. Abandoned or custom extensions present the most common challenges and may require replacement or developer assistance.
Before you act, verify critical technical details such as exact Joomla 4 system requirements and the official upgrade procedure against the Joomla documentation. With careful preparation and a rollback plan you can reduce risk and complete the migration confidently.
This article documents a practical, repeatable protocol to migrate Joomla 3 extensions to modern Joomla versions (4, and forward toward 5/6). It is written for site owners, designers and junior developers who need a structured workflow that reduces risk and helps produce stable releases. The protocol is stage-based: prepare, audit, automated fixes, manual refactor, database work, frontend and assets, testing, packaging and release.
Important: verify any version-specific API or manifest details against the official Joomla Developer Documentation before applying changes in production. Several technical claims below are flagged for verification in the checklist at the end of the article.
Overview: Why a repeatable protocol matters
Migrating extensions ad-hoc often leads to regressions, inconsistent upgrades and surprising support requests. A repeatable protocol helps you:
Limit scope and focus effort on risky areas.
Automate low-risk changes and reserve manual review for tricky API or database work.
Deliver predictable results with clear rollback and test plans.
Expected effort and scope assessment
Classify the extension early so you can estimate effort. Typical categories:
Plugin — single file or small set of files: minutes to a few hours for simple cases.
Module — small UI with a few helpers: a few hours to a day.
Component — admin & site areas, models, controllers, views, DB tables: days to weeks depending on complexity.
Library / system plugin — can be high-risk if it touches core services.
Decision point: rewrite vs incremental refactor. Choose a rewrite if the codebase is extremely old, unmaintainable, or uses patterns incompatible with modern PHP. Otherwise, prefer incremental refactor to reduce risk.
Practical example
A simple content plugin that hooks into events and uses a few legacy calls may be updated in a couple of hours by replacing deprecated APIs and updating the manifest. A component with custom routing, many models and a large custom table requires a full audit, tests, upgrade SQL and multiple staging iterations.
Warnings
Do not run migrations directly on production sites without a tested rollback plan.
Large extensions with custom database schemas have higher risk and need staged validation.
Pre-migration checklist (requirements & backups)
Preparation reduces surprises. Before changing code or database:
Decide target Joomla versions to support (Joomla 4 only, or include planned J5/J6).
Confirm the required PHP versions for the chosen Joomla targets — verify this against official Joomla release notes.
Create full backups: files and database snapshots. Keep timestamped copies.
Archive the current extension installer ZIP to your releases folder.
Set up a local dev environment and a staging instance that mirrors production as closely as possible.
Verify PHP and Joomla core target versions
Before you refactor, check the minimum PHP required by your target Joomla version and plan for those constraints in your code. This affects syntax choices and dependency versions.
Backups and restore plan
Document the exact steps to restore a previous extension version and to restore the database. Example backup actions:
Export DB: run a consistent dump (for MySQL: use mysqldump with routines and triggers if needed).
Archive files: compress the site files or use a filesystem snapshot.
Save installer: copy the installed extension ZIP to an archive directory.
Automated scans can produce false positives; validate each flagged item manually.
Do not remove legacy compatibility classes until verified in a test environment.
Stage 2 — Apply automated fixes and static checks
Automated tools accelerate fixes for repetitive patterns and enforce coding standards early in the process.
Use code-mods or scripted replacements for low-risk, well-scoped changes.
Run PHP CodeSniffer (phpcs) with Joomla rules and address obvious issues.
Introduce static analysis (PHPStan or Psalm) to find type and API usage issues; tune the configuration for legacy code.
If a composer.json file exists, run composer install and validate autoload.
Automated fixes: code-mods and scripts
Automated replacements can be safe for well-known patterns but be cautious. Example safe patterns include adding class aliases or replacing obvious, exact string API calls. Avoid broad regex that can change unintended code.
Static analysis and coding standards
Set up phpcs with the Joomla standard and run it early. Add PHPStan or Psalm incrementally and suppress noise in older code until you can address issues systematically.
Example commands
Run phpcs:phpcs --standard=Joomla path/to/extension
Run PHPStan (example):vendor/bin/phpstan analyse src --level=5
Always re-run the extension's install and basic flows after automated replacements to catch runtime errors.
Warnings
Automated replacements can break code if patterns are ambiguous—always run tests afterwards.
Static analyzers may require tuning to avoid excessive noise for older codebases.
Stage 3 — Manual refactor: code, API, and manifest updates
This is the core of the migration. Manual edits are required for namespace restructuring, replacing deprecated APIs with service-based calls, and updating the XML manifest for modern Joomla versions.
Namespaces and PSR-4 autoloading
Convert legacy non-namespaced classes into namespaced classes and reorganize files to match PSR-4 if you choose to adopt composer autoloading. A typical move includes adding a namespace line and updating class usage across the codebase. If you plan to use composer, include a composer.json with an autoload section.
Example (illustrative only — verify formats with docs): transform
Before: legacy class without namespace
class PlgContentExample { /* ... */ }
After: namespaced class (example)
namespace Vendor\Extension\Plugin\Content; class Example { /* ... */ }
API replacements and service usage
Identify common legacy patterns such as factory calls and replace them with service-based accessors where applicable. These replacements vary by Joomla version and should be verified against the official API documentation before final changes.
Manifest and installer updates
Update the extension XML manifest to include any new required elements and attributes for modern Joomla versions. If you plan to publish via composer, include appropriate metadata and consider whether you will support both traditional ZIP installers and composer distribution.
Practical notes
Move to PSR-4 carefully: renaming and moving files can introduce class-not-found errors if autoloading is not configured correctly.
Retain legacy class aliases while validating all entry points; remove aliases only once the staging verification is complete.
Label any illustrative code snippets in your repo with a clear note: "example — verify against official docs."
Warnings
Moving to PSR-4 changes class resolution—test thoroughly to avoid class-not-found errors.
Do not remove old class aliases until all entry points are validated in staging.
Stage 4 — Database and schema changes
Database changes are often the riskiest part. Plan idempotent upgrade steps and tie them to the extension update mechanism so they run during installation or update.
Upgrade SQL files and migration functions
Structure upgrade SQL files per version pair or use migration functions that check for existing columns. Example best practice: run SQL that checks for the existence of a column before adding it.
Testing database migrations
Always test migrations against a realistic copy of production data on staging. Provide rollback SQL or documented steps for manual recovery when fully reversible SQL is not feasible.
Practical example (illustrative)
Example SQL stub that adds a column only if it does not exist (verify syntax and adapt to your DB engine):
-- Verify this SQL and adapt to your DB engine and Joomla update mechanism
Warnings
ALTER TABLE on large tables can lock the table and cause downtime; consider online schema change strategies or schedule a maintenance window.
Always test migrations against a realistic dataset to detect performance regressions.
Stage 5 — Frontend, templates and assets
Modern Joomla has evolved frontend markup and asset registration patterns. Review template overrides and JS/CSS registration to avoid broken pages.
Templates and overrides
Locate template overrides in the site template that affect your extension. Keep overrides minimal and update layouts to match any changed variables or markup from the refactor.
Assets and JavaScript
Register scripts and styles via the recommended asset management mechanism for the Joomla version you support. Audit JS libraries and remove or update bundled libraries as needed. Avoid inline scripts relying on global legacy variables.
Practical examples
Update a template override that referenced a removed layout variable by adjusting the override to use the new view data.
Replace direct <script> insertion with registered assets where supported.
Warnings
Changing templates can alter frontend behavior—test on multiple devices and browsers.
Replacing bundled third-party libraries may require license checks.
Stage 6 — Testing strategy (local, staging, CI)
Testing should be progressive: start with local manual checks, add automated unit and integration tests, and run these in CI before deploying to staging.
Unit and integration tests
Write unit tests for critical services and model logic. Create integration tests covering install/update, save operations, and permission checks. Configure PHPUnit to run tests for your extension; verify recommended configuration against Joomla testing docs.
CI pipeline basics
Example CI stages: checkout → composer install → phpcs → phpstan → phpunit → deploy to staging. Manage secrets for DB and use lightweight fixtures to keep jobs fast and stable.
Practical example
Sample test matrix to adapt:
PHP 7.4, 8.0, 8.1 (adjust according to target Joomla/PHP requirements)
Joomla 4.x and target future versions you plan to support
Warnings
Running browser UI tests in CI increases complexity; begin with unit and integration tests.
CI jobs must be reliable and fast—avoid unstable external services in test jobs.
Stage 7 — Packaging, versioning and release notes
Prepare the final package and communicate clearly to site administrators. Choose a versioning strategy and build an installer that matches your distribution model.
Packaging options
Decide between a traditional ZIP installer and composer distribution. Both are viable options; contrast them for your audience and document installation instructions for each. Verify current packaging recommendations from Joomla docs.
Release process and support
Include a changelog, compatibility statements (Joomla and PHP versions), known issues and upgrade steps. Provide a rollback plan and support contact for early adopters.
Packaging checklist
Bump semantic version appropriately for breaking changes.
Run phpcs/phpstan/phpunit and ensure green status.
Generate final ZIP or composer tag and upload to distribution channel.
Publish release notes with backup instructions and known issues.
Warnings
Do not force major refactors in a minor release without clear migration notes.
If supporting multiple Joomla versions, ensure compatibility metadata is accurate to avoid installation blocks.
Troubleshooting common issues
Here are typical problems and how to diagnose them quickly.
Class not found: check namespace, spelled class name, and autoload mapping.
Missing assets: confirm asset registration and correct paths; clear caches.
Broken routing: verify route definitions and task handling in controllers.
Language mismatches: ensure language keys and file encodings are correct.
Database upgrade failures: inspect the SQL run by the installer and compare errors in the PHP/DB logs.
Diagnostics and log checks
Enable Joomla debug and check logs in the administrator and server PHP error logs. Use Xdebug locally to step through failing code paths.
When and how to roll back
Rollback process should be documented in the pre-migration plan: reinstall the prior extension ZIP and restore the DB from the backup snapshot. Coordinate rollbacks with a maintenance window if the site is active.
Practical troubleshooting example
Resolving a 'class not found' error: check the reported class name in the stack trace, ensure the file containing that class exists and that its namespace matches whichever autoloader you are using. If you recently moved files, regenerate autoload data (for composer) and clear opcode caches.
Warnings
Frequent rollbacks without addressing root causes reduce user trust—use rollback as a last resort.
Be careful when restoring DB backups on active sites; coordinate with site owners and users.
Tools, resources and quick reference
Recommended tools and quick commands to speed migration tasks:
phpcs (Joomla coding standard)
PHPStan or Psalm for static analysis
PHPUnit for unit/integration tests
Composer for dependency management and autoloading
Git and CI (GitHub Actions or GitLab CI) for continuous checks
Command-line quick tips
Install deps:composer install
Run phpcs:phpcs --standard=Joomla path/to/extension
Run PHPStan:vendor/bin/phpstan analyse src --level=5
Monitor error logs and user reports for 48–72 hours after release.
Be prepared to publish a hotfix if critical issues appear.
FAQ
Do I need to rewrite my entire extension to support Joomla 4/5/6?
Not always. Many extensions can be updated incrementally using automated fixes and focused manual changes. Major rewrites are usually needed only for very old or heavily customized codebases. Perform an audit to decide whether a rewrite is justified.
Do I have to adopt PSR-4 and composer to migrate?
PSR-4 and composer are recommended best practices for modern PHP projects and simplify autoloading and dependency management. Whether they are required depends on Joomla's current extension requirements—verify against the official Joomla documentation before enforcing this in a project.
How do I test the migrated extension safely before production?
Use a local environment matching production, a staging site with production-like data, and an automated CI pipeline. Create a test matrix for PHP and Joomla versions, run unit/integration tests, and perform manual acceptance testing on staging.
What is the safest way to update the database schema?
Use idempotent upgrade SQL files or Joomla update scripts tied to extension version numbers; run migrations on a staging copy of production data first and prepare rollback SQL or documented recovery steps.
What are the most common causes of post-migration breakage?
Common causes include class autoloading issues, deprecated API calls not fully replaced, missing assets after asset manager changes, and untested database changes. Thorough testing reduces these risks.
How should I communicate breaking changes to users?
Publish clear release notes listing Joomla and PHP compatibility, breaking changes, required pre-update steps (backups), and a support contact method. Provide a short migration guide for administrators.
Conclusion
A staged, repeatable protocol reduces migration risk: prepare and backup, audit thoroughly, apply automated fixes, perform careful manual refactors, test in CI and staging, then package with clear release notes and rollback options. Adapt the protocol to your extension’s size and complexity and verify any version-specific technical details against official Joomla documentation before production changes.
Use the printable checklist in this guide as a baseline and expand it with project-specific steps. If uncertain about API replacements or manifest schema changes, consult the Joomla Developer Documentation and consider a small proof-of-concept migration on a non-critical extension first.

CSS has from the age of the Internet been a part of doing websites. It is an easy but useful way to design an article. There are several ways to write CSS in Joomla, you can use an external file to store all CSS codes in, you can use an extension to include the code, or you can write CSS directly in the content. In this article, I will give some look into how I do it.
In this article, I will show you three different ways to use CSS in an article. The easiest thing is to use an extension to add CSS to the article. There are several extensions in the JED (Joomla Extensions Directory) that gives this opportunity. One of the popular is Sourcerer from Regular Labs. But its also possible to do in-line CSS coding in every article, but this can be very ineffective in large articles, the third and maybe most used is to put the CSS codes into the template as eighter an external file or in the CSS capabilities of the template itself. In modern template-Framework is this common, the disadvantage of this is that you always need access to the backend to add extra CSS in your site.
W3C CSS verified: W3c.org is setting the standards for CSS
1 Code directly as you go (Hard coding the articles)
If you prefer to do the CSS coding inline as you write an article, you must bear in mind that you will NOT be able to reuse the CSS on any other articles and you must repeat the same thing for every content with the same code. This could look like this:
If you use an external file as a CSS source, it is normally located under the css folder in your template directory. And its usually called custom.css or user.css, the downside with this is that you need access to either FTP or bee logged in to the backend as a Super Administrator.
3 Use an extension to add CSS code in the article
If you want to use an extension to insert CSS in an article, you can not reuse the CSS codes without having it in every article that contains the same style.
What do I recommend?
A combination of the option 2 and 3, will give the easiest result and you can standardize some of the CSS styles in a file and add styles in that applies to certain articles at one addon at the end of the written article.
