I am trying to create facebook sign-in page according to this tutorial. I only changed the two lines
appId : '370675846382420', // App ID
channelUrl : '//http://bp.php5.cz/channel.html', // Channel File
and I get the following error
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.
What might be the problem?
The problem is that whatever url you are currently hosting your app is not setup in your Application configuration. Go to your app settings and ensure the urls are matching.
