Not sure if this is a technical issue with how to get to publish or a question about publishing so I will reply to both potentials.
For the former, this article is helpful, also before hitting publish I always have a second set of eyes review every single thing on my landing page and cirriculm (I find a friend who doesn't know the topic as best as they will pay attention to new details over things they may skim because they know.) If it gets rejected to fix something, it will take more time when it sounds like you ready to hit publish. Once it's approved it's open to the market and students.
To submit a ticket for any tech issues go here.
Good luck on the new course,
