Hi, my theme was based on twentyten or twentyeleven. I tried changing to twenty fourteen and the issue was still present. i’ve also tried switching off some of the plugins and no joy. The issue has happened suddenly after this site has been using wp-ecommerce for about 3 years without trouble so seems to be since the recent update.
The site is https://www.sarah-janepetwhisperer.com if someone is able to take a look. The wordpress and wp-ecommerce are latest versions.
Specifically, the cart shows no items after you click add to cart, then go to checkout.
Thank you.
