The client somehow clicked the update from VirtueMart 3 to VirtueMart 4 and now the design of the category page and the product page is default Joomla CSS and should be like what was created before. We need a Virtuemart / Joomla expert who can asap resolve the issue and the CSS of the category page and product page is like it was 2 hours ago.
