Hi,

After Upgrade from DNN 07.02.02 to 07.03.03, Scheduler give Next Start 01/01/0001.

When set Schedule Start, it doesn't seem to run the event.

This issue been post on https://dnntracker.atlassian.net/browse/DNN-5642 but seems it cannot reproduce.

Event Viewer give a "Scheduler Exception" with detail info :
