Great plugin, works great except for this bug I found.
Browsing through Google and the Support forums here, I reckon it's not something new and a lot of SFC users are experiencing this problem.
The problem is that the plugin does NOT connect FB User to WP User
I have the Login and Register modules active.
When a new user registers WITH FB credentials, a password is emailed and in Facebook the app displays (Account Settings - > Apps), so all seems to be in order.
BUT the WordPress user account is NOT automatically connected to the Facebook account. (this is where it goes wrong!!)
Then if the user goes to /wp-login.php WITH Facebook logged in, the user is automatically redirected to /wp-login.php?action=register.
(this is probably because the FB App recognizes the user, but since the FB acount is not connected to WP account, the user is not 'recognized' by the site.)
Then if the user fills in the Register form again with the same FB credentials, the WordPress user account is finally connected to the Facebook account. And this is where it gets really strange:
On the 2nd Register try, the user can fill out any username, it does not matter, it still connects the Username entered in the 1st Register attempt to the Facebook account.
Obviously the problem is that the WP UserAccount is not connected to FB UserAccount on 1st Register attempt, but only after the user Registers AGAIN with same FB credentials.
Anyone got any ideas on how to fix this problem?
