Header Navigation Menu

My site is not live so I can’t show you the problem besides uploading a screenshot to google drive. For some reason, I haven’t changed anything but the menu at the top of the page has disappeared. It used to say “Home, About, Courses, Contact” and now it doesn’t say anything.

I have confirmed all the menu settings are appropriately checked in wordpress. I am at a loss of how to fix this.
