My website has an index page, but clicking an image doesn't open up the connected sub-page. I'm on Version 7.0, Montauk family (Montauk template). There's custom code that's affecting the ability of the index's sub-pages to open. I took over this website from a predecessor, but I don't know code.
In the "Website Tools" section of my website, I'm seeing the following:
Header
<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-WFQ4PR9');</script>
<!-- End Google Tag Manager -->
Would someone be able to tell me what this code is doing?
From,
Eric
