Hi,
I am working on a Vantage Premium site and have come across an error message that slows down access to the page loadin and the page view shows a large black banner across the top of the page.
The error warning is:

Hi Gordon,
This was previously reported to us by another user. Basically, product-domain.php is a plugin that your hosting provider has added to your WordPress install. I would recommend contacting them to report this issue and request that the plugin is disabled (or fixed).
