I found this old topic, but this is still not solved.
We have a 3 year old prestashop and now the ps_cart_rule_combination has more than 6million lines in it. In our Cart Rules tab in the BO we only have 900 lines.
Is there a better way to solve the compatibility issues with other cart rules and not maintain a 2GIG ps_cart_rule_combination table?
Thanks for your help! Ryan
