AbleCommerce Shopping Cart Software

I get

Server Error in '/' Application.
Invalid column name 'CountryCode'.
Invalid column name 'ProvinceId'.
Invalid column name 'PostalCodeFilter'.

When trying to upgrade.

any thoughts?

Gonna need some more detail.

Was that during the actual upgrade scripts running against the database, or after the upgrade process completed and site started to load again?

Anything else unusual happen during the upgrade steps? Do any of the store pages or Admin-side load at all?

You probably haven't run the all database upgrade scripts.
