Well, I added a featured image to my post, added another post, also with a featured image.

I also reset all the defaults in the theme setting.

This seems to have fixed this issue. Thanks!

Yes, I know that now. But the main issue is that I re-installed wordpress altogether, reinstalled the theme, and still got the error without touching anything.

I just did it all over again. Heres the site: https://www.civurban.com

Well, yes, I was messing around with all sorts of stuff, and broke it.

But, the point is, I uninstalled the WordPress install, re-installed, re-downloaded the theme, and tried it all over again. And I kept getting the same odd behavior.

yes, getting the same issue. I have the same exact error message / 404 issue. Any reasons this happens?
