It sounds like the version you upgraded from could not automatically update the db structure. I can fix this but I would need temp access to phpMyAdmin and a temp admin account in WordPress. The access to phpMyAdmin is needed to assess the current db structure. The WP admin access will be used to manually trigger the proper upgrade functions. The access info can be sent to me using the contact link at the bottom of the page. Please paste a link to this forum thread in the message so I can relate the two. Thanks and apologies for the trouble.
