The system will notify you when you reach your order limit.
Nothing will disappear from your calendar -- courses, classes, and workshops all stay -- but you won't be able to create new orders for them.
You can still create courses and workshops beyond the limit, but they won't be displayed in the public schedule.
Course limits
In addition to the order limit, some plans also have a limit on the number of active courses you can have at the same time. If you've reached this limit, you won't be able to create a new course until an existing one ends or you upgrade to a higher plan.
Tip: If you see a message that you've reached the course limit but some of your courses have already finished, check if they are still marked as active. Completing or archiving finished courses will free up slots for new ones.
