  <p>I'm developing a Facebook app. When I attempt to get an access token, I get the following message:</p>
  
  <blockquote>
    <p>An error occurred with test. Please try again later.</p>

  <p>I've configured the app's domain (<code>appsdot.xxx.com</code>), name and other attributes.</p>
  
  <p>What is causing this error, and how do I fix it?</p>
