Facebook login in grails error

Facebook login in grails error

I want to allow my users to login with facebook account. I'm using
Facebook SDK for JavaScript.
https://developers.facebook.com/docs/facebook-login/getting-started-web/
So my problem is:
When I click on the login button to login with facebook account. I get the
error given below;
"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."
Maybe there is settings problem I guess. Can anyone help me ?
Thanks Smac
