TypeError: 'undefined' is not a function (evaluating '$(document)')

Question

1. I\'m using a WordPress site.
2. I\'m including this script in the header.

When the script loads, I get this error:

TypeErro

Answer 1

I had this problem only on Chrome.

I tried adding

var $ =jQuery.noConflict();

just before calling

$(document).ready(function () {

It worked.

Thanks a lot
