I get the following error messages in the System scanning log
Mailing Operator '=' is not defined for type 'DBNull' and type 'Boolean'.
Mailing Divide by zero error encountered.
Mailing Operator '=' is not defined for type 'DBNull' and type 'Boolean'.
The Mail-Reports don't work as expected. I created a Mail group and activated several mail reports.
Most of the mail-reports don't work. Some do work, but all of them are reports which I created several months ago. All of the newly activated reports don't work.
How do I solve this problem ?
Kind regards,
Martin
