As I added my older posts and verifying that they published, I noticed that they were showing up on the front page but when I clicked on any of the posts, they would not show.
I did a bit of researching and found that my .htaccess file was not writeable to WordPress so I changed the permissions. Still not working. Did more research. I came across this answer that I did not have the AllowOverride directive enabled. Duh! So used the Server app and logged in and hit the checkbox for my site to allow overrides using .htaccess.
I can now go to sleep.
