.htacess ErrorDocument 404 and php

[Sims]

Hi,

I have the strangest error with my .htaccess.

I have something like
ErrorDocument 404 /error/error.php?err=4 04

But that does not work for php file?

If I look for www.example/test.html, (<= test.html does not exist), then the
error.php file gets loaded, but if I look for www.example/test.php, (also
does not exist) then the standard 404 page gets loaded.

Any reason why that would happen?
