Extensions Extension Manager Database
This screen is accessed from the back-end Joomla! administrator panel. It is used to check and fix any database issues with your website.
How to Access
- Select Extensions → Manage → Database from the drop-down menu of the Joomla! Administrator Panel. Or select the Database menu item in the Extension manager screen that appears.
This screen checks that your database table structure is up to date with your Joomla programs and lets you try to fix any problems that are found.
In a normal Joomla version update, changes to the database table structure (also called "schema") are done automatically to keep the database version synchronized with the Joomla version. If an update is done manually, or if some part of an automatic update fails, the database schema might not be updated to match the version of the Joomla program files. In this case you will see a list of database problems on the screen. You can normally fix any problems by clicking on the Fix button.

The functions are:
- Fix. This program attempts to fix any database table structure problems found in the Database check. It runs any database schema change scripts (from the folder
administrator/components/com_admin/sql/updates) that were not run during the version update. It then re-checks whether or not the database is up to date. If it is successful, the message "Database table structure is up to date" will show.
- Options. Opens the Options window where settings such as default parameters can be edited.
- Help. Opens this help screen.
