Upgraded from DNN6 to DNN7.1.2.
No 3rd party friendly URL provider installed.
I switched the urlFormat from humanfriendly to advanced. I then created a 404 page (not included in menu, permissions set to viewable by all users).
When I try to browse to a page that doesn't exist, it doesn't go to my new 404 page.
What else do I need to set up?
