Are you sure that’s the Twenty Fourteen theme? I see this:
Positive.
And while I’ve got your attention I have “buddypress-activity-plus and bp-group-documents” plugins and no matter what I do only admins can upload docs. I went so far as to change the group settings in the db “group_documents_upload_permission” to “members” and admins are still the only one’s who can upload.
I guess I should have pointed out that this is as you scroll up
I can’t reproduce the problem. Do you have any plugins activated aside from BP? I’m using the latest WP (4.3.1) and BP (2.4.0).
