I have a site at the root of my /http/
folder (I’m using Apache).
In a subfolder, I have another WP site. When a 404 is encountered within the subsite, like this:
www.mysite.com/subsite/thisDoesntExist/
the 404 page for www.mysite.com
comes up – instead of the 404 for www.mysite.com/subsite/
Can I make the subsite catch these 404 errors?
