First, I want to thank you for developing this plugin. It's a nice simple alternative to flashier overdone e-commerce plugins.
I was in the process of implementing the plugin earlier. Everything was working fine and then suddenly, after clicking "Add to Cart" from my products page, it stopped going to the Cart page.
I know the checkout page exists, because I can see it when I manually type in the url. But for some reason, it's stopped going automatically after I select my product.
