I don't believe this issue is related to the Login issue that has been a problem from Facebook Connect's side, so I split this thread off into it's own topic.
When you're getting that message, is it on both this site (
www.sourcecoast.com) and the demo site (
sourcecoast.com/jfbconnect/demo)?
Have you ever tried creating an account on either site before, and were you able to log in then? Or is this the first time you've tried?
Either way, that's not a normal error to get, and I'm unsure why it's occurring just for you. We get dozens of registrations a day through Facebook, and today, they seem to be working as expected, so would like to get more information in case we're missing something.
Sorry for the troubles, and thanks for the feedback.
