Hello everyone,

I have just enabled logging in to the forums using Facebook connect. The feature is new to vbulletin and has a bug when existing users try to use it.

New registrations work OK.

If you are an existing user try this to get it to work
  1. Login using the regular login forum process, not Facebook Connect
  2. Go to the connections tab in your user profile settings.
  3. Activate Facebook connect using your Facebook email address and password
  4. Log out and then login using Facebook Connect and your Facebook email address and password.

Let me know if it works for you.
