I have 3 total pages on my site plus a “Home” page. On two of the pages, all 4 show up on the navigation menu but the other two pages the same one page is missing from the navigation menu. The customization screen shows all 4 pages on the navigation menu while viewing each page, but when viewing the pages while not logged into the admin section of my site then it isn’t working as described above.
So after dealing with the support from my web host I discovered that the changes that I make to the appearance/theme do not reflect on each page until I have updated every page individually then refresh my browser. Since my home pages shows my latest posts I have to republish an old post or publish a new one in order for the home page to reflect the appearance changes.
