“Hey PressKey. I was checking out your site and there seems to be a problem with the shopping cart.

In Firefox on a Mac – I clicked “Add to cart” and the little popup showed that it was added. But the total at the top didn’t update, and if I click on View Cart, it’s empty.

In Google Chrome on a Mac, Same as above, but the cart total updated at the top, until I changed pages.”

Please could you advise how to fix this issue.
