I’m using version 2.8.2 and also get an error when trying to publish an entry. Additionally, dates are not editable, all dates display as:
November 30, -0001, 12:00 am – 12:00 am
Failure: Try again? SELECT scheduleID FROM wp_schedule WHERE schedule_title = ‘Skillset 2’ and schedule_date = ” and schedule_description = ‘test’
