My back page is https. The page with the embeded code is a local html just for testing. I have tried Firefox and Chrome with and without extensions. So far no luck

Also devtools tell me the error is here

/******** Script loader function ********/
   function script_loader( url ) {
      var script_tag = document.createElement('script');
      script_tag.setAttribute("type","text/javascript");
      script_tag.setAttribute("src",url);
      // Try to find the head, otherwise default to the documentElement
      (document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
      return script_tag;
   }
   

jquery hasn't been loaded. File not found. Error on the line 72 of the embed.js

Enable Storefront Embed is set to ON

This error I get in Chrome Developer Console

GET file://back.yaskan.com/index.php?rt=r/embed/js net::ERR_FILE_NOT_FOUND

Apparently, the embed.js file is not seen or accessible.
