I would recommend just adding the missing fields manually as it states in the debug section you can also use the file database_updates.php as reference. also make sure you set the latest db version in the settings table once you update all fields. This should clear it up. It might be tedious and will take a bit so just take your time.
To note your setup is not ideal for updates and will cause issues going further potentially more as we start implementing more features and db changes. We will be offering hosting and support soon so that could be a benefit to you. Keep an eye out on our main page.
