Cart not clearing
After the creation of a guest sign in, I ran some tests and everything seemed to be working just fine.
However, I happen to notice that the cart was not cleared or emptied after a complete and successful transaction. The cart still showed the original items to be purchased.
Of course, this appeared to be a problem if a shopper wanted to go back and make another purchase. Are you able to determine what the cart may be doing?
I have provided my cart.php page for your convenience.
