@dangerin: Please post screenshots for: AdminCP (mostly the left navigation area), Forum Home (mostly the navbar section), UserCP (left navigation again). Please note that the connection button doesn't show up with logged in users
@Zaiaku: You can test it on my demo board. Please note that if the Facebook user who commented on one of the published post and his/her comments get synchronized into forums, the time he/she try to register (or connect the Facebook Account with an forum account), all the post will be updated to associate with the forum account.
@BBR-APBT: Thank you for the fix

Brilliant!
