Hi @foxweb09,
It seems your theme is running a very old version of jQuery. Since update 5.5 WordPress dropped the migrate script to jQuery 3.0. Complianz also requires jQuery 3.0, so that is why the banner does not appear. While inspecting your site, I see several other console errors (right-click -> console while visiting the front-end of your site).
You can load jQuery 3.5 by inserting this script (preferably in the site footer):
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
Please note that your version of jQuery is known to contain security issues as well, so it might be worth considering to switch to a different theme.
Kind regards,
Leon
