If I click on "Proceed to checkout" page is reloaded but is blank

Dear Kriesi,

I have three problems with the cart

1) if I add a product to the cart I see a blank page

2) if I navigate back I see the cart icon on the top right

if I click on it and then on “View Cart” or on “Checkout” I am redirected to the same product page.

3) If I navigate manually to the page http://new.profumo.it/en/cart/ I see the product correctly inserted in the cart, but if I click on “Proceed to checkout” page http://new.profumo.it/en/cart/ is reloaded but it is blank.

This with all plugin disabled (except WooCommerce)

Thank you Mauro
