I have bought this theme in 2013, I have a version for joomla 2.5 and virtuemart 2.0. It is version 2.0, I guess.
When I did some upgrades on virtuemart, the file upload stopped working, and add to cart function stopped working and some other functions. Can I update the functionality without updating the design? When I purchased the template, I was promised lifetime support and update. My website is document-service.ru (now it is off, because most functions don't work). I would appreciate your help.
