D2L Incident #
In the Edit Course > Manage Dates tool none of the tools have any effect. This includes Edit Dates, Offset Dates, and using the red x icon to remove a date. The tools go through their steps and report they saved successfully, but no changes are made.
Manually changing each date in the appropriate tool. For example, to change the date of a quiz, the quiz must be edited in the Quizzes tool.
