Change the order of your scripts from

<script src="js/plugins.js"></script>
    <script src="js/scripts.js"></script>
    <script src="https://apps.elfsight.com/p/platform.js" ></script>

to

 <script src="https://apps.elfsight.com/p/platform.js" ></script>
    <script src="js/plugins.js"></script>
    <script src="js/scripts.js"></script>

I have a problem with this site: http://www.gm-impianti.srl/index.html

when I open the site, and from the menu, i open the “portfolio” page, the instagram plugin is not loaded. If I load the page again, the plugin works. why?

this is the js that is not loaded on the first start:

<script src = "https://apps.elfsight.com/p/platform.js"> </script>

thanks in advance
