Your site looks to be using a very old version of JFBConnect. My first suggestion would be to upgrade to the latest release, v6.1, and see if that fixes your problem.
If that doesn't help, or you don't want to upgrade, that's fine. We'll gladly help however we can. For further assistance, please post from the account you subscribed to JFBConnect from. Priority support is for active subscribers only.
Thanks,
