Products not adding to cart

Hi,

using marketpress 2.3.2 and gridmarket 1.2

The problem is when you click on the "add to cart" button, it used to be that the item was added to the cart and you sae the change in the cart area,now after updating to the latest versions this no longer happens.

We have to "force" issue by clicking on another category before anything shows in the cart.

To recap:

1. click on add to cart (nothing is visbly added even thoguh you are informed that it has been)
2. click on another category and the item appears in the cart

To check this out please go to:

Cheers
