WordPress Chat Endlessly refreshes for Facebook

Howdy,

I've tried to set up WordPress chat on two sites now and Twitter authentication works just fine, but whenever I try to work with Facebook it becomes unusable.

Once I authorize the app, the page goes into an endless refresh loop. Then, when I try to enter the page in another tab, it also goes into an endless refresh loop.

You can try it out on a 2011 installation with no plugins here: http://hermpheus.andrewsfreeman.com

Any help is appreciated.
