title: Facebook comments plugin screams: Warning:URL unreachable
body: <p>Please check www.turie.eu
  It displays yellow box with Warning: <a href="http://www.turie.eu/" rel="nofollow">http://www.turie.eu/</a> is unreachable. When you click on that url, it goes to facebook linter and displays:</p>
  
  <pre><code>Critical
  Invalid app ID  ID application "{135765723173532}" specified in meta tag "fb:app_id" was invalid.
  Error
  Invalid app ID  ID application "{135765723173532}" specified in meta tag "fb:app_id" was invalid.
  </code></pre>
  
  <p>I'm absolutely sure that the ID is ok and the url is fine too. Any ideas? Thank you!</p>
