Good day.Try in phpMyadmin to do the query (ALTER TABLE `oc_product_to_category` ADD `main_category` tinyint(1) NOT NULL DEFAULT `0`; and gives me : #1146 - Table `seltik_ocar897.oc_product_to_category` doesn`t existÐто means the request failed? And what`s the problem?
Answer:
Hello.
the error stated that no such table exists. Check the correctness of a set of named tables and fields.
