Good morning to everybody,
I've upgraded prestashop from 1.7.7.5 to 1.7.8.2 and I've a problem, when remove a product from cart, the cart won't update. The product is deleted but I to refresh the page to see.
This problem occurs only in the cart page https://www.mydomain.xx/en/cart?action=show if I try to delete the product from the sidebar in every other page excecpt from cart page I don't have the problem.
Same thing is occcur in another one website where the upgrade was perfomed from 1.7.7.7 to 1.7.8.2.
Any help is appreciated because I don't receive any error in debug mode and no error show on apache error.log
Sorry for my poor english 
UPDATE
I saw in the apache access.log when I perfom delete action from cart page the log write only this:
"POST /it/carrello?delete=1&id_product=8831&id_product_attribute=0 HTTP/1.1"
instead when I perform a delete action from cart sidebar in other pages the log write this:
"POST /it/carrello?delete=1&id_product=8831&id_product_attribute=0 HTTP/1.1"
"POST /it/module/ps_shoppingcart/ajax HTTP/1.1"
"POST /it/carrello?ajax=1&action=refresh HTTP/1.1"
seem to be a problem with the a missed ajax call
