title: Error with FancyBox grouped elements (Requested content cannot be loaded)
body: <p>I'm trying to do an image group with fancybox (I'm also using twitter bootstrap, etc)</p>
  
  <p>However I'm getting the following error when the FancyBox "popup" appears:</p>
  
  <pre><code>The requested content cannot be loaded.
  Please try again later.
  </code></pre>
  
  <p>Here's a test case that reflects my issue:</p>
  
  <pre><code>&lt;!DOCTYPE HTML&gt;
  
  &lt;html&gt;
      &lt;head&gt;
          &lt;meta http-equiv="content-type" content="text/html; charset=utf-8"&gt;
          &lt;title&gt;Test&lt;/title&gt;
          &lt;link href="scripts/fancybox/jquery.fancybox-1.3.4.css" rel="stylesheet "type="text/css" media="screen"/&gt; 
      &lt;/head&gt;
      &lt;body&gt;
          &lt;ul&gt;
              &lt;li&gt;
                  &lt;a class="grouped_elements" rel="group1" href="#"&gt;
                      &lt;img class="thumbnail" src="http://placehold.it/90x90" alt&gt;
                  &lt;/a&gt;
              &lt;/li&gt;
              &lt;li&gt;
                  &lt;a class="grouped_elements" rel="group1" href="#"&gt;
                      &lt;img class="thumbnail" src="http://placehold.it/90x90" alt&gt;
                  &lt;/a&gt;
              &lt;/li&gt;
              &lt;li&gt;
                  &lt;a class="grouped_elements" rel="group1" href="#"&gt;
                      &lt;img class="thumbnail" src="http://placehold.it/90x90" alt&gt;
                  &lt;/a&gt;
              &lt;/li&gt;
          &lt;/ul&gt;
          &lt;script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"&gt;&lt;/script&gt;
          &lt;script type="text/javascript" charset="utf-8" src="scripts/fancybox/jquery.fancybox-1.3.4.pack.js"&gt;&lt;/script&gt;
          &lt;script type="text/javascript" charset="utf-8"&gt;
              $(document).ready(function(){
                      $(".thumbnail").click(function(){
                          $("a.grouped_elements").fancybox();
                          });
                      });
          &lt;/script&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Any ideas ? </p>
