HTML embed code is not loading in wordpress

Hi,

I was given this HTML embed code by a merchant for whom I am an affiliate. I placed it in a page as raw text. Sometimes the page loads properly but sometimes it doesn’t. I am using Visual Composer, so when I realised the page is not loading propelry I took the code out of the basic WP Text Editor and placed it in a VC ‘Raw HTML’ module. But again, same problem: the page does not load properly. I tried placing it in a VC ‘Javascript’ module, with the same result.

This problem only occurs in Chrome; in Firefox the page loads fine.

Could you please tell me where I should be placing this code snippet?

Many thanks!

PS. I have changed the domain info in the snippet below (for security reasons).

<div id="mysites-root" class="thissites-root-product63891"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "https://anydomain.subdomain/embed/EmbedCode/0/0/0/0/1914?site=https://anydomain.thissite.product"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'thissites-js63891'));</script>
