Hi, thanks for the tips. I am having the same problem upgrading from Prestashop 1.7.7.3 to 1.7.8.7 version. I tried replacing the file with the core.js provided here and clearing the cache. Actually after that the cart works, but it seemed to work badly, because it was much slower to update than on the original site. I tried to reset the ps_shoppingcart module, but this makes the cart completely disappear from the site, and if I try to add a product to the cart nothing happens. And consequently any addition of products to the orders is impossible. The cart page, on the other hand, can be reached, but only using the specific link. Updates of the quantities of products already present in the carts can be made, but they are always as slow as before. I have done these operations on a "demo copy" of my site, then an http site, if that could affect it.
