There are quite a few reasons that could cause what you're describing. We should be able to help, but need to know a lot more about your configuration. Can you let us know:
* The URL of the site or page you're having issues with?
* Are you using JFBConnect? If so, what version?
* How are you configuring the Open Graph tags on your site?
Beyond that, please post from the account you subscribed to JFBConnect from. Priority support is for active subscribers to JFBConnect only.
Thanks,
Alex
