At a glance
A lesson is pinned to a day that is not part of the school week.
What causes this error
A lesson has been manually pinned to a specific day, but that day has since been removed from the school's active days. The generator cannot place the lesson.
How to fix it
- Re-enable the day — Go to the schedule settings and add the day back to the active working days.
- Unpin or repin the lesson — Go to the Lessons section and either remove the pinned day or change it to an active day.
