Hi,
I have many problems with Prestashop 1.7.5.1 and later versions. I am a newbie.
When adding a product to my cart, the page refresh does not work, and the cart seems to be empty. However, it can be seen that the product has actually been added because when the page is refreshed, the basket shows the product.
The updates worked correctly before, but I can not tell at which version of Prestashop or PHP the problem started to occur. I noticed the problem during the update to version 1.7.6 because products could not be added AT ALL to the cart, and the quick overview did not work either. I went back to version 17.5.1, but the problem persisted. I also downgraded the PHP version, but the update did not work. Being a beginner with Prestashop, I prefer asking for help from more experienced people before creating fatal damage.
I also tried disabling the non-Prestashop modules (there are only a few), but that did not change the situation. I do not have the Google Analytics module (I think).
Where could the problem be?
Thank you in advance.
