I’ve noticed the CSS isn’t applied to the 404 page. This page link above is a non existent page so should display, as it does, with the oops message. All good there, but I’d like the CSS from the rest of my site to be applied, like on this page: https://hostabout.com.au/about-us/
Do I need to change any PHP for this to happen? Or can a Child CSS be sufficient?
