title: Fancybox: The requested content cannot be loaded. Please try again later
body: <p>This particular topic has some answers on SO, but none of them solves my problem. I have no idea where to look here, although I suspect it's something very simple.</p>
  
  <ul>
  <li>When I try to open a url in a Fancybox <strong>manually</strong> (i.e. by 'physically' clicking a link) it works. </li>
  <li>If I however try to open it on page load <strong>automatically</strong> (i.e. by faking clicking a link), it doesn't work at all and gives me the error I mention in my title.</li>
  </ul>
  
  <p>The HTML is simple:</p>
  
  <pre><code>&lt;a href="http://www.mydomain.nl/url/to/whatever" class="fancybox hidden_link"&gt;test&lt;/a&gt;
  </code></pre>
  
  <p>The Javascript I'm using to automatically click it, is pretty straightforward too:</p>
  
  <pre><code>$(document).ready(function() {              
      $(".hidden_link").fancybox().trigger("click");
  });
  </code></pre>
  
  <p>The event goes off (a Fancybox opens), but it shows nothing more than the 'content cannot be loaded' message.
  I see my own page in the Fancybox when I click the link manually.</p>
  
  <p>What am I missing here?</p>
