Unfortunately, that does not work.
I tried to remove the items, but they don’t show up in the admin panel.
It might be caused by removing items directly through webdav and not through wordpress. Also, items which were manually uploaded in the same directory are not visible in the file manager interface.
Does the plugin look for actual assets inside the wp-content/uploads/user_uploads/user folder? If not, how do I make it look for actual assets in the user_uploads folder?
