Q:

mysterious 404 error

When you load this page, a 404 error appears in Firebug
NetworkError: 404 Not Found - http://summer-festivals.cloudfoundry.com/undefined

My best guess is that some javascript var that should resolve to an image, .js, or .css file is undefined, but I'm not sure how to go about tracking down the code responsible.

A:

If you have console open while the page loads you see the error on a stack:
