Whew! Thanks for resending the credentials and your patience. The issue was that the following error was being thrown during the authentication process:
SSL certificate problem: unable to get local issuer certificate
That usually means that the SSL root certificates on your server are out of date. These are the certificates that validate *other* servers, not the SSL certificate for your site itself.
This is a common issue, but usually a better error message is thrown when you try to authenticate instead of requiring us to do the debug we did. To fix, please set the "Disable SSL Verification" setting in the JFBConnect -> Configuration area. That will bypass the SSL verification process, which decreases security by a slight amount. However, data between your site and the social networks are still encrypted and private.
I hope that helps, but if that setting doesn't get you going, please let me know.
Thanks,
Alex
