eCart 5, after checkout the cart is not cleared
I am using the eCart 5 (with session variables, MacOSX and CS4) and my checkout is to send an order list via e-mail.
The problem: when I made checkout the cart is not cleared.
In fact (after I have made chekout and sent e-mail) if I go in the catalog for a new checkout and I click on "Add to Cart" button, when I view the cart the new product is added to the privious cart.
Besides, I don't know if it is for the same cause, but I notice that the Order Number after it has arrived (with auto increment) to the fifth record, now it stopped at 5 and it modifies this record insted of increasing.
Thank you very much.
