When somebody adds an item to the cart and then presses checkout, it sends them to the old domain name.
The URL is domain.comindex.php?page=checkout.index&ssl_redirect=1&option=com_virtuemart&Itemid=215
when I press checkout on the new domain it sends me to the old domain, I checked the headers and it says 303 HTTP/1.1 303 See other
Please don't send him a pm, or if you must, post the answer here so other can benefit.
What is it with pm's, pm's are for off topic IMHO if it is about VM then please post the answer so we can all benefit!
You need to go to virtuemart configuration to change the domain.
specifically
components/virtuemart/admin/configuration/security tab
also, if you have a sef component, like artio, ace, or sh404, purge their caches, check you config file for joomla to make sure the live site url is correct, if using a htaccess file, make sure there are no directives there that could redirect to the old domian
