This page:
http://www.dragonavenue.com/assdf
shows the entire 404 template page as expected. No style, no header, footer, etc. Just a blank page with a some text.
However a post page 404 looks like this:
http://www.dragonavenue.com/dnd/post/pagethatdoesntexist
It is clear to me that the redirect code only changes that template, not really redirecting the browser to the template page alone. I am confident that this is because the redirect code is within the “post_container” page which is embedded in the “post” page.
To be clear: the template called “post” has the post_container embedded within it.
(I know that seems backwards - I’ll fire the guy who came up with that naming convention later)
