title: colorbox shows "Request unsuccessful: error" on chrome
body: <p>I am trying to load content from a html page on my colorbox when my page is ready, using:</p>
  
  <pre><code>$(document).ready(function(){
      $.fn.colorbox({href:"popup.html",'width':'750px', 'height':'700px'});  
  });
  </code></pre>
  
  <p>It works fine on every browser but chrome, which shows in the colorbox popup "Request unsuccessful: error". What am I doing wrong?</p>
