I recently (today actually) merged an SMF forum to XenForo, I installed the latest version of XF and also the latest version of the media gallery post-SMF convert. Now my converted user account can access the admin area but none of the gallery option, I get a "You do not have permission to view this page or perform this action." error. Now my other admin user account that I made when I first installed the XF can access all media gallery options. I've even went into my user account that was converted and set the permissions to use the gallery but no luck.
