I backed up and ran an update for WordPress and my websites' plugins. Now the sub items in the navigation bar are not visible. They are published/public. I can access them in the backend as pages.
I do not know if this is a result of the update/something to do with the code. Should I restore the WordPress back to the backup? Or is this something to do with changed code? (Not sure if the website was set up with custom code or not...)
