Then I watched the tutorial “create-a-front-page-like-the-demo-site” to try and make further changes. However, the page that looks like my front page that I’ve already altered isn’t visible in the PAGES section of WP. I took a screen shot of the home page and the list of pages.
After reading your response I went to WordPress Settings >> Reading and see that I can select a page. But I’m not sure how to convert the front page header into an actual page…so grateful for your advice!
