Just upgraded from 2.3.something to 2.5.5 and lost our 404 pages. We don’t have strict URLs enabled because we only use one template group for our pages, and like the cleanliness of the URLs (e.g. /about).
It used to be (before upgrading) that when a visitor hit site.com/template_that_doesnt_exist they were shown our 404 page. Now, though, they get the site homepage.
I see there was a bug fixed in EE 2.4 that relates to this, but I’m not sure if that’s what changed.
Or perhaps I’m missing something?
