Ultimate Facebook and footer hiding the facebook registration

I have a problem with a theme and ultimate facebook.

When activating “register through facebook” wp-signup.php it seems to put the footer content over the facebook registration.

I tried to overide the setting in the wp-signup.php by html style

#menu-footer-menu{ display: none;}

#footernav { display: none; }

registration page…

It works on wp-signup.php but as soon as fb_registration_page is in the url

then it doesn’t seem to remove footer content.

Am I missing something obvious?
