Course Invitations are not being sent

Community Novice


I've recently started having an issue with my canvas course. It's been published for 3 years, and for the last few weeks, when I try to add a learner it states that invitations will not be sent until the course is published. It is published. I do not know what changed from one day to the next, but I need to add learners and another instructor. Please help! Any ideas?
