Tinkered some. Not sure what I did, but all links, posts, etc. are now working.
All other Main Menu buttons are working properly.
BINGO!! That did it. Thanks for hanging in there with me!
Are you asking did I click on “Blog” for the category of my two trial posts? If so, I did.
That did not do it. Front page is set as “A static page” and I went to Posts > All Posts and entered “Blog” in the categories for my two trial posts. All I get when I hit the “Blog” on the menu is ‘Blog’ appears where I expect to find my posts.
