I've implemented the Social Plugin for WordPress on a site I'm creating (culturedvalet.com). I've tested all logins and they work except for FB. It does ask for the registration info of the user, but doesn't seem to save it. When pressing the button again, it no longer requests the information, just refreshes the page apparently. I tested with several FB accounts as well as different devices just to make sure. Plugin version is latest out.
Please advise and thank you for your time.
