I could only ever get it to automatically register once. After logging out, I couldnt log back in. I deleted the user from the joomla backend end (which had an invalid email address, like facebook_334524165254@invalid with no @), but when I tried to sign in again I couldnt, no matter what, whether in canvas or stand alone mode. I tried about 60 times, and it just doesnt do anything excepr reload the page as if i clicked refresh.
