can't get facebook login to work!?

my site is myucirvine.com
i have enabled the plugins and inserted the correct ip and secret, but it won't work.
If you press, it asks to sign in to facebook. Then you press login, and the facebook windows disappears without logging in?? It just wont connect??
Please help. Thank you!
