Hi, we’re getting some issues on uploading .pdf or .docx to a cifs external storage that’s being used as a group area.
The following show the error that we get, I’ve tried to disable the plugins that we’re using, but the error persists:
Is it an external storage which is mounted from a user’s personal page or by an admin user? Do you use encryption app? Did you delete some users (the invalid user message) or use external authentication backends?
If you say renaming doesn’t work, so you can’t upload any file?
