Front page 404 error

If that page is automatically loading, it means you have the Automatically Login Facebook Users enabled, and JFBConnect is simply trying to automatically log you in.

As for the 404 error, that's odd for that page to throw an error like that. The component should definitely be there, obviously. Can you check the following:
* Go to the Joomla Extension Manager and search for the JFBConnect component. Make sure it is "Enabled"
* Check that you can properly access the JFBConnect Administrator area. Check that the versions are up-to-date
* Disable the Auto-Login Facebook Users setting, enable the SCLogin module and try logging in by manually clicking the "Login with Facebook" button.

Let us know if any of that helps narrow things down.

Thanks,
Alex
