Ultimate Facebook Connect Login Looping

Hi. I am having an issue ever since updating Ultimate Facebook to 1.5.0. I now have 1.5.1 and the bug is still present. When a user clicks "login", the loading animation appears and just keeps looping. The user is logged in, but there is no redirect or new page load.

I tried reverting to the standard theme and deactivating plugins, but nothing seems to work. I'm using the latest WP and BuddyPress versions. Please help.
