This is just so weird. So it worked without the Context Setting, using only the System Setting for "error_page". Then I somehow lost (deleted?) the resource, so made a new one, assigned it to the error_page key in System settings, but now I'm back with the default 404 / 503 error page.
I have not setup any FURLs so my urls are all /index.php?id=123 when I got to /index.php?id=12abd I get the 404 / 503 error, but when I go to /404 or /test or /bla, I'm redirected to the homepage.
Then, in desperation, I tried to add the error_page key back to the Context Setting. Lo and behold, there's my 404 page.
This is just
ridiculous, modx team, you can't ship a product with such unpredictable behavior.
First and last time I'm using this
