i have some JS problems in my new Prestashop website. Fancybox seems to create conflict. This is the error in Chrome console
Uncaught TypeError: $(...).fancybox is not a function
at HTMLDocument.<anonymous> (custom.js:216)
at u (core.js:39)
at Object.fireWith [as resolveWith] (core.js:39)
at Function.ready (core.js:39)
at HTMLDocument.H (core.js:39)
The website is taglioestampa.it
It's because your theme do not use Fancybox. so you need to include fancybox JS script.
it's located here :
so add before
<script type="text/javascript" src="https://taglioestampa.it/js/jquery/plugins/fancybox/jquery.fancybox.js" ></script>
