Page header is requesting theme resources by HTTPS

Dear all,

I’ve a problem with the Quest theme: the files needed by the theme and included in the page HEAD tag are requested by HTTPS protocol, while in the web site there is HTTPS active. This causes the web pages not rendering well because the browser cannot download those files under HTTPS.

Below some example:
<script type=’text/javascript’ src=’https://xxxxxxxx.eu/wp-content/themes/quest/assets/plugins/bootstrap/js/bootstrap.js?ver=4.4.1′></script&gt;
<script type=’text/javascript’ src=’https://xxxxx.eu/wp-content/themes/quest/assets/plugins/smoothscroll/SmoothScroll.js?ver=4.4.1′></script&gt;

Thanks, F.
