TYPO3 Core

Editors with two or more allowed languages can select the function "Languages" in the page module. But without the permission to the default language this results in an error.

1. Create editor with a limitation to two languages (not default langage)
2. Login as editor and switch to the function "Languages" in the Page module

=> The error message "Call to a member function getTitle() on null" occours because of the missing permission to the default language.

Another issue is the missing "Languages" function (Page module) for editors with only one language permission (not default language). This occurs because of the following performance fix: https://forge.typo3.org/issues/89125 . With that the function is only visible with a minimum of 2 allowed languages.
