I am very new to Zen Cart, and I am not a programmer . When we go into the store, or when a customer goes in, they click on the desired item and click add to cart and get a blank page. No error message, just a blank page. If you use the back button and go to the top of the page, the item has added to the cart. So you go to the next step and click the button to proceed,l and again get a blank page,l no error message, just white. It keeps working if you use the back button and click on the "My Cart" at the top of the page, until you get to the payment options, where it just blanks out and nobody can buy anything from my store. Please help.
