title: Facebook login in grails error
body: <p>I want to allow my users to login with facebook account. I'm using Facebook SDK for JavaScript. <a href="https://developers.facebook.com/docs/facebook-login/getting-started-web/" rel="nofollow">https://developers.facebook.com/docs/facebook-login/getting-started-web/</a></p>
  
  <p>So my problem is:</p>
  
  <p>When I click on the login button to login with facebook account. I get the error given below;</p>
  
  <blockquote>
    <p>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.</p>
  </blockquote>
  
  <p>Maybe there is settings problem I guess. Can anyone help me ?</p>
  
  <p>Thanks
