Hi Aray
By default the content bottoms modules do not have an ID to link to, To amend try adding the following to the
Head Custom Code field of your templates parameters (Extensions -> Template Manager -> YourTemplate -> Custom Code -> Head Custom Code)...
<script>
document.addEventListener("DOMContentLoaded", function() {
document.querySelectorAll('.wrapper_contentbottom').forEach(element => {
element.id = 'wrapper_contentbottom';
});
});
</script>
This will add an ID of
wrapper_contentbottom
