title: Facebook Invalid Scopes error on test app
body: <p>All of a sudden I'm getting an "Invalid Scopes: manage_pages" error during login in the <strong>test version</strong> of my Facebook app. 
  The full error message is:</p>
  
  <blockquote>
    <p>Invalid Scopes: manage_pages. This message is only shown to developers. Users of your app will ignore these permissions if present. Please read the documentation for valid permissions at: <a href="https://developers.facebook.com/docs/facebook-login/permissions">https://developers.facebook.com/docs/facebook-login/permissions</a></p>
  </blockquote>
  
  <p>The live app is working fine.
  Everything was working fine in the test app as well until this morning.</p>
  
  <p>If I read the provided docs link it looks like <em>manage_pages</em> permission is still in use.</p>
  
  <p>Anybody has an idea of what could be wrong with it?</p>
