Joomla Help Screens

Maintenance: Database
Description
This page checks that the database table structure is up to date and tries to
fix any problems that are found. In a normal Joomla version update, changes to
the database table structure (also called a schema) are executed 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 the page will list any database problems discovered. It is often
possible to fix any problems by selecting the Update Structure button.
