How to change in Prestashop to have only one cart rule (voucher) in the basket

Prestashop combine cart rules /vouchers (coupons) in the basket.


Even when we setup all settings corectlly, some old vouchers can be still combined and used with another ones.



This small fix will apply to all vouchers to not combine them.


  1. Just open your phpmyadmin and access table ps_cart_rules
  2.  open sql query tab
  3. write command and click go
SELECT * FROM `ps_cart_rule` WHERE 1;
 update ps_cart_rule set cart_rule_restriction = 0
