Bug: JavaScript undefined function (and consequences)

Hi !

I had a problem with Shortcode Ultimate Spoilers block which were inactive on some browsers including Chrome.

I discover that there was a Javascript Report error in the Chrome console :

Uncaught ReferenceError: Cookies is not defined(anonymous function) @ use_cookie_when_ready.js

Looking at the file :

jQuery( document ).ready(function() {
	var cookie = Cookies.getJSON('wp_user_stylesheet_switcher_js');

Other error were also indicated in the same block :

m.Callbacks.j	@	jquery.js:2
m.Callbacks.k.fireWith	@	jquery.js:2
m.extend.ready	@	jquery.js:2
J	@	jquery.js:2

So, I desactivate WP User Stylesheet Switcher, and the console indicates no error at all,and this resolves my Shortcote ultimate prblem, proving that a Javascript errors came from WP User Stylesheet Switcher.

Can you please solve this issue ?
