Greetings,

It seems that you haven't run the database upgrade scripts for 4.2 -> 4.3, which are responsible for adding those columns to the database.

In order to upgrade nopCommerce and all our products, you need to run our upgrade scripts as well, as per our instructions on upgrading nopCommerce.

Hi. I'm facing the same problem. Where can I find those scripts to update from 4.2 to 4.3?
