Login with Facebook doesn't login?

Got this up and running but when clicking 'Login with Facebook', the popup opens, I enter Facebook credentials, I'm told that the app will access my email, wall etc, so I allow. The popup closes but nothing else happens, and I'm not logged into my site? I have obviously missed something but I have checked and doubled checked, and read other threads. I need a pair of eyes outside the tent looking in! Website is http://wantrid.com Facebook page is http://facebook.com/wantrid

Many thanks.
