When I activate Social Access Control, the Media Library becomes empty, i.e. it lists the count of pictures/videos it contains but no pictures/videos are listed.
Note that I installed Social Privacy as explained.
To get to this conclusion, I did deactivate all my plugins, then reactivated them one by one.
I don't think it is linked to the WP version as I updated only yesterday to 3.1.2 and already had the problem with 3.1.1.
Anyone with the same problem? Any idea how to fix it...?
