Jim,
There looks to be a few issues.
1) You have another Facebook extension enabled, but configured incorrectly. I think it's part of your Gavick template. You should disable the social (and especially FB Login) features of that entirely if you want to use JFBConnect.
2) The JFBCSystem plugin doesn't look to be published.
Fix those 2 things, and you should be good to go.. or at least in a much better spot!
Thanks,
Alex
