title: facebook debugger URL returned a bad HTTP response code
body: <p>I've created a shop site for one my customer.</p>
  
  <p>Facebook debugger send to me many errors:</p>
  
  <pre><code>Could Not Follow Redirect Path Using data from 
  http://www.yupeshop.it/IT/prodotto.php?id=84&amp;label=Sciarpa+Stampa+con+fantasia+UK 
  because there was an error following the redirect path.
  </code></pre>
  
  <p>But there is no redirect. URL returned a bad HTTP response code.</p>
  
  <p>But if I try to get the page with an online check I see 200 OK as answer, what's wrong?</p>
