I'm not sure if you are telling me to report a bug or read the bug report for migrate-imp-to-turba. I did disable migrate-imp-to-turba as suggested and it stops the error messages when I reboot the server. However, I cannot get into my email via Webmail. I have tried to log in with the folder-prefix set to "Mail/" (the default), blank and "/". None work, I receive the error message detailed in my first message. Also, with migrate-imp-to-turba enabled, the error message at bootup is not the same as that shown in the bug report.
