You should open the file administrator/components/com_hikashop/install.hikashop.php and search for that column name. You should see something like that:
$this->db->setQuery(“ALTER TABLE `#__hikashop_YYYY` ADD `XXXXXXXX` ……………………………………………..”); $this->db->query();
You need to open your phpmyadmin and run the query which is in the double quotes in your database. Don’t forget to replace #__ by the prefix of your tables.
For custom fields, you can just delete them and the error should disappear.
