title: Integrating filemanager in CKEditor error
body: <p>I'm trying to integrate filemanager (<a href="https://github.com/simogeo/Filemanager" rel="nofollow">https://github.com/simogeo/Filemanager</a>) in CKEditor and using php connector but browsing doesn't work (keeps loading forever) and if I try to upload a file I get this error</p>
  
  <pre><code>Uncaught TypeError: Cannot read property 'Code' of null 
  </code></pre>
  
  <p>This is filemanager.js</p>
  
  <p><code>var data = jQuery.parseJSON($('#uploadresponse').find('textarea').text());
              if (data['Code'] == 0) { ...</code></p>
  
  <p>the result from <code>$('#uploadresponse').find('textarea').text()</code> is empty.</p>
  
  <p>As I said, I'm using PHP connector and default configs. I tried to access the files directly (not through ckeditor) putting in the browser <code>http://127.0.0.1/filemanager/index.html</code></p>
