tyrasyantel,
There's a few reasons that those messages could be occurring in your error log. The first thing to note though is that you're using a version of JFBConnect which is more than a year and a half old. Things have changed with Facebook integration substantially since then and we no longer test that version. My first suggestion would be to upgrade to v5.1, which is the latest available, has great new features like Google+ authentication, and is known to work.
If you'd rather us help you diagnose the really old version you're using, we gladly will. If so, please post from the account you subscribed to JFBConnect from as priority support is for active subscribers only.
Thanks,
Alex
