Need some urgent help. I'm running the latest version of your eshop and am having this bug with empty carts.
e.g. Pick an item you want to buy....add to cart.... proceed to checkout and then it says that the cart is empty. Therefore no one on my site can check out. Could you please help. Here is a link to one of my items on the site: http://toyporium.com.au/2011/01/23/nerf-n-strike-longstrike-cs-6/
Please try to check out and see the issue I'm talking about.
I am happy to make a small donation for a quick solution to this issue.
Thank you for you time.
