Thanks for the Private Message with your site details, and sorry for the delay in getting back to you.
When I go to the JFBConnect Overview page on your site, I see the following errors:
Facebook API Error: name lookup timed out
Facebook API Error: name lookup timed out
That indicates that your server isn't able to do the required DNS lookup to translate the name 'facebook.com' into the IP address that it needs to communicate with. That communication is obviously critical for JFBConnect to work as we need to be able to talk to Facebook quite a bit.
Can you talk to your hosting provider or tech support to see if there's a block or some other configuration issue that may be causing DNS lookups for any of the following addresses:
https://api.facebook.com
https://api-video.facebook.com
https://api-read.facebook.com
https://graph.facebook.com
https://graph-video.facebook.com
https://www.facebook.com
Hope that helps get you started and helps make some progress with the issue. If you still need further help, just let us know. I checked a few other things on your site, and everything else looks setup correctly and ready to go, just so you know.
Thanks,
Alex
