Cart Rule "controller Not Found" Error

[Cha Wang]

Since upgrading from 1.4.5 to 1.6.1.2 we have this error in cart rule: Controller not found

 

With this we cannot create any voucher or coupon. How to solve this problem?

It might be missing. Check if you have AdminCartRulesController in controllers/admin

Well, it has always been there. Any other reasons? Can we reinstall the cart rule "module" one more time to make sure all the files and databases are properly linked?

I'd like to mention that in the situation of the Google site map, the admin interface of the module gives a different name than what it actually generated. This caused a 404. Could there be some naming of files in the case of the cart rule? What file could have been mis-named? I am suspecting this because when we were using 1.4.5, we employed a community developed module: Lofcoupon, when we first installed it it didn't work. The developer entered our admin and ftp area to fix it. Could they have written something in our database/files to over-rule the native cart rule?

 

Here is the list of database tables we have for cart rule, if this info is of any use for judging what is going on:

ps_cart_rule

ps_cart_rule_carrier

ps_cart_rule_combination

ps_cart_rule_country

ps_cart_rule_group

ps_cart_rule_lang

ps_cart_rule_product_rule

ps_cart_rule_product_rule_group

ps_cart_rule_product_rule_value

ps_cart_rule_shop
