Hi @ayrpin,
I see that your theme attempts to load a very old jQuery function ‘msie’ which was used to detect Internet Explorer. Because this function is not supported anymore since jQuery 1.9, this causes a jQuery error on your site. You can see this yourself by right-clicking on your site -> inspect -> console.
Because Complianz requires jQuery and loads in the footer, the banner does not appear (because jQuery is no longer working).
I would strongly advise you to update your theme, as running these old jQuery versions can be a serious problem in terms of security and compatibility.
You could also try to locate the function that tries to use the msie function, to delete it, but that would be some custom work and the security concerns remain.
I hope this helps.
Kind regards,
Leon
