Guest check-out problem

Hi,

I set in WooCommerce settings “Enable guest checkout” and after adding an item to cart by guest visitor (I get a message that it was successfully added), but when I visit cart (or checkout page) there is a sentence “Your cart is empty” and no products are displayed. When I use logged-in user the cart seems to work fine.

If you need please use the username I sent you earlier for makieta.wpengine.com
