My only guess, then, is that this perl script runs at a URL that does not match the path of your other page, and that your external script in "java/fancybox/source/jquery.fancybox.js?v=2.1.4" can't be found relative to your URL. Try opening the page with Chrome*, press F12 to open the Developer Tools, then view the Network tab to see if there are any 404s. You might also see JavaScript errors in the console.

* If you don't have or don't want to use Chrome, Firefox has similar Dev tools.
