There's a few possible reasons for your issue:
* When I try to login, the following message is thrown in the Javascript console:
Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.
That's usually a sign that you haven't run Autotune lately and configured your Facebook App properly. Can you re-run Autotune and in the FB App section, hit "Refresh". Make sure all the settings are correct and save your changes.
* There's a Javascript error on your page. Facebook is heavily dependent on Javascript, so problems in other extensions can cause issues. The error I'm seeing is:
Uncaught SyntaxError: Unexpected token < oakeuze.js:1
That's not from JFBConnect, but hopefully that helps you narrow down where the problem is.
Let us know how that goes, and good luck,
Alex
