My Shopping Cart was working fine up until Friday. I had one person purchase a product on Friday morning, and then it stopped working. You can add products to the cart and they show up in the shopping cart widget, but when you go to check out or just go to the shopping cart, it tells you that the cart is empty. When you navigate back to a product page, the shopping cart widget is empty. However, if you add a new product, all of the old products show up. However, they all disappear again when you go to checkout.
None of this behavior was occurring for the last month until Friday morning. However, the shopping cart does work when I am logged in as the administrator. Even more strange, the shopping cart works from the Chrome Browser on my Android phone! Please help. The site is: http://www.keystolivingexpo.com
