To avoid conflicts with other sites, and ensure that your page's URL always includes your subdomain (dept.barnard.edu is a subdomain), always set a domain-specific path for the page. This does double duty as the site does not recognize the menu hierarchy, and the path to a deeper page must be set here.
Find your subdomain and enter the page's path so that is the same as what was entered under menu options. For example, for a main menu item titled Major Requirements, you would enter major-requirements.
Until Published is selected in this section, the page will remain in draft state which is not visible to visitors.
