Uncaught TypeError: a.indexOf is not a function” error on load

[mimouni]

This error might be caused by jquery event aliases like .load, .unload or .error deprecated since jQuery 1.8. Look for these aliases in your code and replace them with .on() to register listeners instead. Example:
fakeLoader.js [line:120]
$(window).load(function(){...});

becomes:

$(window).on('load', function(){ ...});
