What exactly do you mean by "ran setup"? Upgrade process happens in admin panel, not setup directory.
I mean that I did this..
"To run the upgrade script, simply login to admin panel or point your web browser to http://www.yourdomain.com/osticket/setup/upgrade.php(http://www.yourdomain.com/osticket/setup/upgrade.php), replacing www.yourdomain.com/osticket(www.yourdomain.com/osticket) with the correct URI to your own osTicket installation. When prompted login as admin - the script requires admin level privileges - and follow the instructions."
