I am having a problem with my shopping cart for wp. It seems that I am making transactions but my paypal and google account checkouts are not logging transactions that are taken place on my website. They say it is a configuration with the plugin I am using and not their sites. What should I do? I uploaded up-to-date themes for wp-ecommerce themes through wpa storefront but I don't see any changes. My customers are unable to checkout and that can be very hurtful for me as a business owner. Help!
