Hello, i'am new to OPR and most things work and only one thing ist a problem.

I wand to upload a PDF-file of 100kB unter Documents in a Projekt, but receive the error "Die Datei wurde von einem automatischen Filter abgelehnt. 'application/pdf' ist nicht für Uploads freigegeben." (in english "The file was rejected by an automatic filter. 'application/pdf' is not enabled for uploads.").

What have i done wrong or where did i set the file format filters?

There is no additional file storage (Nextcloud) attached to OPR, just the file storage of my virtual machine.

Thx 4 help
