 * I got this to work on one of my sites, but another site on the same domain(but
   different directory) gives me this error after I made the facebook app and try
   to connect:
    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.
 * I tried to make another app and it does the same thing. Do I need to change something
   to make it work?

 * Hi c,
 * Please make sure you add your site to your app using the “Add platform” button
   on the bottom of the App Settings page. Then you can add your domain as a App
   domain in the same screen.
