The issue is that your jQuery library is loaded over http and fails since it's a different protocol from the main site. More info regarding this here: https://developer.mozilla.org/en-US/docs/Security/MixedConte...

To fix, simply change http://cdnjs to //cdnjs to make your request protocol independent.
