I'm trying to duplicate a store for testing purposes. The original store uses a custom domain. I have the duplicate store set to use a foxycart subdomain. When I add something to the cart, I get take to the correct place, i.e. the cart for the duplicate store, with the foxycart subdomain. But when I proceed to checkout, it takes me to the original store's checkout page, under the custom domain. I can't figure out why this is happening. There's nothing in my cart template that refers to that domain. When I cache the cart template, there are still no references. But when I pull the cart up on the site, under the correct foxycart subdomain, the source is full of references to the original site's custom domain. It's like the new store is pulling the original site's cart template. How could this be happening?
