Thanks for your reply. The (spam) settings for minimum number of posts etc. are all set to 0 because the forums are private (all members get access only after approval of Forum Admin).
It has something to do with wpForo access rights, because the Forum Admin can upload attachements in the forum without any problem (after uploading topic attachment it is added to WP Media Library successfully), but if wpForo Admin tries to upload a Forum Cover image he gets wpForo message (not allowed to upload files).
@mhit ,
It's already fixed. You will receive the fix in the new version of wpForo.
Hi, I just installed the new wpForo version 2.2.1 but the problem with uploading forum cover image ("no permission to upload files") still exists.
I have cleaned all caches and logged out / logged in.
The Forum Admin (wp user role is "subscriber") is unable to upload Forum Cover or choose a forum cover file from media library. However he can succesfully attach images to forum topics so there seems to be no problem with access rights for forum attachments. Only uploading forum cover or choosing a forum cover image causes error message for access rights.
(Forum Admin usergroup also has all 'can' options tagged).
The Forum Admin (wp user role is "subscriber")
What user role is assigned to your ordinary registered members?
