Maintenance (Admin Tools)

Only available if typo3/cms-install is installed.

The backend module Admin Tools > Maintenance offers tools to system maintainers that are necessary during development or updates.

Some of the tools available here include:

Flush TYPO3 and PHP Cache

By clicking the button Flush cache you can flush all caches. This is necessary during development if you changed files like Fluid templates, TypoScript files, or PHP files.

It is also necessary to flush caches after installing or updating extensions.

You can achieve the same effect by calling

ddev typo3 cache: flush

Note

Flushing the cache via the "Clear cache" buttons in the Top Bar does not have the same effect. It does not flush PHP related caches.

Analyze Database Structure

Aside its name this tool does not only analyze the database structure but also offers to fix it for you.

Database changes can be necessary when TCA files where changed or extensions installed / updated.

Create Administrative User

This tool can be used to create a new administrative backend user with or without maintainer privileges.

You can also create a new backend user from the console:

ddev typo3 backend:user:create

and from the module System > Backend Users. The latter cannot grant system maintainer rights but is available to all admins.
