Deprecation: #67991 - Removed ext:cms

See forge#67991


Extension cms has been removed. Most functionality has been moved to extension frontend with version 6.0 already. The rest of the files have now been moved to other extensions, extension cms does not exist anymore.


Language files from EXT:cms are moved to different places into the core. LLL:EXT:cms/... references are rewritten dynamically to the new file locations, but this fallback layer is subject to be removed with CMS 8.

Third party extensions that define a dependency to extension cms will get their dependency rewritten to core on the fly during extension installation as a compatibility layer.

Affected Installations

All 3rd party extensions using language labels from extension cms or defining a dependency to extension cms in ext_emconf.php.


Update the dependency constraint in ext_emconf.php of the affected extension. A typical substitution is a dependency to extension frontend.

Move the following references to the new location of the language file:
