What's difference between both websites? The second website (video-production) does not load jQuery and Edge files.
You can look at my screenshots.
Edge 1.5.0 and jQuery 1.7.1 are missing (left panel).
Edge 1.5.0 and jQuery 1.7.1 are loaded (left panel). Therefore, it works fine.
So, is it a path or folder issue ("edge_includes" missing)?
Screenshots are from Safari 6 and Mac OS Lion.
I tested other browsers.
Chrome, Firefox, Opera and Internet Explorer 10 (OS: windows 7) return the same result: no animation on http://motioncity.com/video-production.
