Problem with authentication via Facebook

If you created your Facebook Application recently (after ~August 5th), please make sure you are running JFBConnect v6.1.2. Facebook made a large change on that date that forced a new release from us. All older apps, created before that date, will work with JFBConnect v6.1.1 and lower for the next 2 years. All new apps need to be using our latest release to import user data.

I hope that helps, but if you're running 6.1.2 and still have issues, just let me know.

Thanks,
Alex
