I am building my first-ever WordPress site (http://authormartinroth.com). The Home page is fine, and I can update it as necessary.
I have published an About page (http://authormartinroth/about-martin-roth/), but when I try to view it online I get an HTTP Error 404.0 message (Not Found). It says the requested URL is http://authormartinroth.com:80/about-martin-roth/.
Something is wrong, but I simply don't know where the problem lies. I would really welcome some guidance.
