Extension talk:GroupPermissionsManager/CustomTabs

German mediawiki Version 1.25
After I installed the extension, the Wiki stops with this error message: Fatal error: Call to a member function addMessages on a non-object in \extensions\GPManager\GPManager.php on line 50. Please advise.

Stable, But Parent Archived?
How can this feature be green-stable, along with its sibling Extension:GroupPermissionsManager/ExtendedPermissions, if the parent extension, Extension:GroupPermissionsManager is archived?
