If i click on Add To Cart, the page refreshes but nothing happens. No product is added to the cart. I can only fix this problem by two ways:

1. If i disable the DHWC Ajax plugin, adding a product to your cart works fine. This means there is something in the plugin.
2. If i remove add_theme_support( ‘woocommerce’ );, adding a product to your cart works fine.

I can give you login info for the admin side.
