I used that article, because I had the same problem with the 404 error and it fixed it. Except I don’t know why it broke in the first place. I want my blog to show up at https://fyc.net.r2k2waterbox.com/blog/, but when I set the addresses for the WordPress address and the blog address it came back with the 404. What do I need to do to make the blog show up at the page I need it to?
