title: Test facebook/javascript with local host?
body: <p>I just created an app in facebook to get appid, but I don't have a real website or so, I need to test it on my localhost, is that possible to leave the 'website url' field blank and test it?</p>
  
  <p>When I try to FB.login from my javascript I keep getting a dialog with this:</p>
  
  <blockquote>
    <p>An error occurred. Please try again later.</p>
  </blockquote>
  
  <p>Is this caused by I don't have a proper URL?</p>
  
  <p>Thanks in advance!</p>
