UFB Problems - Stuck on authenticating & buttons unstyled/not working


I am unable to get the Ultimate Facebook Plugin to work. I have similar problems to other members who have posted their problems recently. I have also tried the suggested fixes without luck.

The problem is two-fold.

1) The extended permission section in the settings just keeps loading. This is from the UFB settings.

2) The plugin adds the 'Login with Facebook' Text by login widgets and wp-login page, but it is plain text with no link and not styled as a button.

Any ideas? I had previously used the WP-FB plugin but seeing as I am a paying member of wpmudev I thought best to use the Ultimate Facebook plugin than pay for the premium version of theirs.

Any advice appreciate.
