Morning Ray,
After i have changed the session to cookie a few things have changed. The good thing is the image of the item added to cart is now showing, so it stopped changing the url, on the other side in the cart the continue shopping button and update button do not work and when i close the browser and reopen the cart is empty... so i the cookie is not set...
Can you please have a look at the cart file http://www.promocaototal.pt/listacompras.php and use http://www.promocaototal.pt/continente.php to add items to cart.
Many thanks
Joao Silva
