The issue you are facing:
If I open the note (Notizen) App it woun’d show me my notes:

I tried

  • to deactivate the notes App and activete it later.
  • to manueal reinstall NextCloud.

But it don’t work.

I can create new Notes over the App but It wont show me my old entrys. The old Data are still in the Notes Folder:

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
<?php
