WP e-Commerce 3.7.5
In Firefox and IE7 everything is fine when it comes to sessions, but in Opera by going to the checkout cart is empty. Tested the other site and there also noticed a problem with the session.
I must admit that we are slowly beginning to discourage this script.
In addition, in another post mentioned a problem with fonts in the checkout form. Remembers after completing the form content. The content of this restores the next time you purchase with broken encoding.
