What causes this error
The total duration of all configured periods added together exceeds 1440 minutes (24 hours). A school day cannot be longer than 24 hours.
How to fix it
Go to School Config → Periods and reduce the duration of one or more periods, or remove some periods, so the total stays within 1440 minutes.
