Facebook Registration Pro Sites

Hey guys, i'm having trouble setting up the Ultimate Facebook plugin for users to register with facebook on my pro site.

When i try to register with facebook on the /wp-signup.php page it goes through the whole process, the Facebook popup comes up and says "You've just registered for Bandhouse using your Facebook account.
If you didn't mean to do this, you can undo this below."

Then a browser pop-up shows saying ' send non-secure form' i click yes.

The page reloads and i'm at the exact same spot that i started off, no new website was registered.
