500 Error on changing variants in General topics Posted October 13, 2020 Hi all, Hope you will be able to help me finding (and fixing) a bug that seems to be the same as described above. I have a shop (version 188.8.131.52, PHP 7.2, default/classic prestashop template) and everything works fine.... except product variants. When a user opens a product page to select different color of that product, the page displays a message "An error occurred while processing your request" under the "Add to cart" button. The inspect console tells that the server returns "500 Sever Error", saying "Oops, something went wrong." Log on the server says "POST /index.php?controller=product&token=7c5103bec05826f1beae2462fd282f67&id_product=102&id_customization=0&group%5B2%5D=8&qty=1 HTTP/2" 500 Does anybody know what can be the reason and how to fix this? I'm not sure where to look for a reason and I'm not too skilled to debug and analyze the source code. I can implement a fix in code if somebody will tell where to fix and what.
