Fancybox is not a function in prestashop 1.6

[Przemysław Suszek]

I have very strange problem. I have two online shop. Both are on the default theme. Both has the same module which allow to add user email to newsletter by display pop-up. In the second one the website doesn't load

 

<link rel="stylesheet" href="/js/jquery/plugins/fancybox/jquery.fancybox.css" type="text/css" media="all" />
<script type="text/javascript" src="/js/jquery/plugins/fancybox/jquery.fancybox.js"></script>

 

And of course in conole I have

$(...).fancybox is not a function

 

The question is. How to check why in one website everything is fine and in the second is problem. The same themes. The same module. Different results.

Kind regards

first make sure jquery and facybox.js load correctly,

then make sure the $(...)  object existed,

Who's calling 

$(...).fancybox

? 

Maybe it's calling before loading fancybox library.
