Facebook Login not working

My template is up to date, and so is the facebook plugin (I just downloaded both and re-installed). The API and secret key is filled in the the plug in, the plug in is enabled and auto registration is set to yes. The template social API section has the API entered and "Use Facebook login" set to yes. "Allow User Registration" is set to yes.

Every time I attempt to login with facebook, I get "An error occurred. Please try again later."

As far as I can see the set up is the same as in other Gavick templated sites that I have done where the Facebook login does work (coffe template).

I can find no errors. Any ideas?

I purchased JFBConnect, installed and got it going. It works very well and does exactly what I wanted.

I am not sure what is going on with Gavick's Facebook Login, I am sure they will eventually get it straightened out.
