My nextcloud instance only move folder without files to trash


My trash folder don’t work since a long time.
I tried to clean all trash-folder and to clean file cache (with commands) etc. all what google says but nothing worked.

I noticed that he only move empty folder. He does not move files and folders with files to trash and erase it instand.

What can it be… How can i fix it?
