I have three pages on my website: Home, Blog, About and one project, which is my Portfolio. The pages are all visible when I view them on my computer and via mobile phone.
But the “project” aka my Portfolio isn’t showing up when I look at my site using a mobile phone. In fact, when I checked the dropdown Customize menu [Customizing ==> Home Menu] it shows project as invalid.
How do I fix this so that (1) the project is valid and (2) my portfolio displays on mobile devices? I attached a screenshot.
