What this setting controls
Instructor conflict warnings work like room conflict warnings but for instructors: when you create or save a class, the system checks if the chosen instructor is already teaching another overlapping class. If a conflict is found and the setting is on, an alert dialog asks for confirmation before saving.
How to enable
Go to Admin → Settings → Calendar → Admin - Check conflicts on creation → Instructor. Turn on and save.
Combined warnings
If both Room conflict warnings and Instructor conflict warnings are on and both types of conflict apply, the dialog title becomes "Overlap detected - Instructor + Class room" and lists every conflicting class.
