Slider not showing with mailchimp query string in URL

Hi there,

There is a campaign running in Mailchimp that uses the root url, however, to track clicks MC appends a query string to the URL. When clicking that link, it redirects ok but the slider is nowhere to be seen. I’ve checked the source and it’s not being output at all so there are no JS errors to consider. I had some conditional code around the slider for different pages but have tried removing that completely but still the same outcome..

I’m totally stumped! Anyone have a similar issue?

Thanks,

Rob.
