You may face issues with Joomla when reinstalling it is the best solution.

Our customer support team used this tested approach to resolve hundreds of issues.

In this post, you will learn how to easily reinstall the Joomla core files and database to their default state.

Understand the Problem

This approach won't fix all of your issues. It mainly works for ones caused by the Joomla core.

These types of issues often show up after you run a Joomla core update.

If for some reason, for example, server resource exhaustion or a bug, only some files get updated, you may often see fatal errors or strange usability issues.

For example, you may see that your admin drop-down menus stop working.

Or you may find out, that you are not able to create new items.

The same upgrade works fine on another site.

In such scenarios, try the following.

Create a Backup

Create and download a backup of your site, just in case something goes wrong.

Step #1. Fix Your Joomla Core Files Permissions

Step #2. Reinstall Joomla Core Files

  • In your Joomla backend, go to Components > Joomla Update:

Go to components joomla update

  • You will see the Joomla Update screen. Click the Check for Updates button:

  • Scroll down the page and click the Reinstall Joomla core files button:

Pro tip: If the issue persists, simply download your Joomla version installation package and unzip it into your Joomla root.

Step #3. Fix Your Database Schema

Finally, let's make sure the database schema is OK.

  • Go to Extensions > Manage > Database:

Go to extensions manage database

  • You will see the Extensions: Database screen. Click the Fix button:

Click the fix button

Conclusion

Now your Joomla core files and database should be reinstalled.

If you're still experiencing the issue, then it's likely a bug in the Joomla core or a bug in an extension, but you're one step closer to narrowing it down.
