Currently have ecommerce website which uses Zen Cart and have google analytics installed on it. However the reporting for google analytics has stopped working properly in that it does not deliver which products have been purchased through a normal checkout process or through paypal. It will only report to google analytics if a product has been purchased through Google Checkout. So when you log into Google Analytics and go to Ecommerce section it does not report transactions which have been made through paypal or through the normal checkout on the website. Only transactions, products sold, etc are reported for orders made through Google Checkout. I need Google Analytics to start reporting transactions made through paypal and the normal checkout procedure again.
