Example: Notification(Error): UnhandledException: Invalid column name 'NotifyByOutgoingMessage'.
Cause: The DB sorting is not CaseInsensitive, and therefore a field “Ab” and “AB” are different. The update script does not run. The same problem with a new installation with a Case Sensitive Default
Solution: Set the character set to something Case Insensitive (“_CI_”). My default is “Latin1_General_CI_AS”.
