Everything works fine with the plugin when I add a product to the shopping cart, but when I try to ether delete the product or change the quantity it redirect to the single post template but with the product info in it (I setup the products as a custom post type). The strange thing is that the URL is still the same from the checkout page. I am wondering why this is happening. I checked out some examples sites you guys did and this doesn't happen. I need some help with this please.
Here is the dev site: http://squareone.whackdesign.com/store/. Add a product and try and delete it from the the checkout page and you'll see what happens.
Thanks in advance for your help.
