The tutorial shows how to fix “An error occurred while updating an object. product ()” error in PrestaShop.
You can get this error in the process of adding or editing the product in PrestaShop when PrestaShop 22.214.171.124 template is installed into PrestaShop 126.96.36.199 version.

ALTER TABLE `ps_product` ADD `pack_stock_type` int(11) UNSIGNED DEFAULT '3'; ALTER TABLE `ps_product_shop` ADD `pack_stock_type` int(11) UNSIGNED DEFAULT '3'; ALTER TABLE `ps_pack` ADD `id_product_attribute_item` int(10) UNSIGNED NOT NULL AFTER `id_product_item`; ALTER TABLE `ps_pack` DROP PRIMARY KEY;
