Get that sql error when trying to enter orders-page either in admin side->components->Hikashop->Orders or in Hikashop and via the Orders-menu->Orders.

So mainly, the problem is that I can't get to Orders-page at all.

This happened after I updated my starter-version to the business version.

Hi,

The problem seems to be that you created your MySQL table with a "latin1" collation instead of "'utf8_general_ci" or vice versa.

Please backup before anything.
