title: jQuery colorbox not showing main box but fading the background
body: <p>I am using jQuery colorbox to show some HTML content on my website. This has been working fine up until recently but I am now having issues. My Code:</p>
  
  <pre><code>$("[rel^=ShowCrossSell]").colorbox({
              innerWidth: "600",
              innerHeight: "500",
              iframe: true,
              opacity: 0.75,
              title: 'Please select one or more alternatives ...'
          });
  </code></pre>
  
  <p>and I have a link with a ref of ShowCrossSell_something. This part is working because I get the faded background that the colorbox creates but the main box doesn't show. When I look at the source in FireBug I see the main div has <code>display: none</code> set which is causing the issue. Setting this to inline makes my content appear.</p>
  
  <p>My question is, has anyone else experienced this and if so, what was the cause? I have removed all my other jQuery includes I have added recently but this has not helped. </p>
  
  <p>p.s I am only using jQuery as a library .. no others.</p>
  
  <p>Thanks.</p>
