I'm having many problens with Ultimate Facebook. In fact, it simply don't works. These are my issues:
1 - When I click on "grant permissions" in the settings page, nothing happens. None new window or popup box shows up. Earlier today, the loading icon just loads indefinitely, and the facebook it is never accessed.
2- When I click Login With Facebook, on the login page, the facebook authentication window it's open. But after make login on facebook, i'm not redirected to any other page. I stay in the login page. My facebook e-mail is not imported to my Wordpress site, and none new user is created for me. The only thing that appears to happens, is that the Profile Picture of my facebook profile overwrite my wordpress profile picture. Also my Wordpress Facebook App was added no my account settings>>apps on my facebook.
3 - On the signup page, I can fill the registration form with my Facebook credentials, but the site ask me over and over again, to inform a name for my new blog, even if I don't want one.
I'm using Wordpress 3.3 multisite and Ultimate Facebook 1.6
