Can't edit Scheduler entry if Schedule Start Date/Time is set


For some scheduled tasks listed in the Scheduler, clicking the pencil icon has no effect. Other entries for scheduled tasks may be edited as expected.

Environment: DNN 9.2.0


View records for scheduled tasks using the following query:

select * from Schedule

If the tasks that cannot be edited have a date listed in the ScheduleStartDate column, the issue is due to a known bug in DNN 9.2.0.


  1. Back up the Schedule table before making changes.
  2. Set this parameter to NULL for all scheduled tasks using the query below:
    update Schedule
    set ScheduleStartDate = NULL
    This will overwrite all the dates for the attribute ScheduleStartDate for all tasks.
  3. Confirm that the solution worked by editing the tasks from the Scheduler.
