ICInfo,
Do you have any information about your configuration? We didn't get any information about the configuration for the user that started this post, and have never heard of this issue with the many, many user's of JFBConnect. When you save any of the settings in JFBConnect, do any stick, or is it just the Facebook keys that don't stick?
Any information you can give about your setup would be very helpful, and if it's urgent to get this setup, to speed things along, you can Private Message us credentials for your site so we can investigate further.
Thanks,
Alex
