Now I created a user as a contributor, unfortunately the Quicktag menu does not show up in the visual editor when creating a new post. Why? In the text-view those buttons with all my quicktags show up. But not in the visual editor… the menu is missing.
When I am logged in as an admin, the menu does normally show up. How can I get the menu into the visual editor for other users, too?
No, there are no errors in the console of Chrome. As I said, I am the admin and main user of the blog. Here the AddQuicktag Menu is shown and works correctly. Every other user-role does not show the menu at all. AddQuicktag just works for me as an admin.
I cannot see why, there is also no plugin or similar that hides such functions or something.
