Also no theme files or plugins have been updated. Only wordpress 4.8.
The server has mod_rewrite enabled. I have 400 other domains on the same server and nobody else is having an issue. I’m not sure who has 4.8 installed but this site just started having issues today.
I’ve reset permissions, checked the .htaccess and verified it’s default, verified it wasn’t the php version, reinstalled WordPress 4.8 and the issue still remains.
Just happened to one of my sites as well. I can use plain and custom with /index.php/%postname% but without the /index.php the page gives a 404 error.
Running 4.8 so I’m not sure if that’s the issue.
