If you receive an error message in your general journal saying ‘TransTypeDoesNotExist’ then this could be because you have deleted a setting, for example a standard text.
You are receiving this error e.g. because the deleted text is in the journal. (You cannot see it but it is on the server).
In order to remove this error and proceed you will need to insert a standard text on the line where the error is, save the line and then delete the standard text again and save the line again.
