Very sorry for the delay. I do see the redirect loops, but don't know the exact cause from what I can see.
Can you verify that you have both the Authentication - JFBConnect and User - JFBConnect plugins enabled on your site? If either of those are off, you may see similar behavior to what's happening.
Beyond that, it may be best if we can have a look at your admin area. If that's ok, can you private message super admin credentials? You can PM me by clicking the mail icon under my name to the left. If that doesn't work, let me know and I can suggest a few other things to check.
Thanks,
Alex
