Problems getting 404s

[David J. Weller-Fahy]

Running:
FreeBSD 5.3 release branch
mathopd-1.5p3       A very small, yet very fast HTTP server
php4-cgi-4.3.9      PHP Common Gateway Interface
php4-mysql-4.3.9    The mysql shared extension for php
php4-pcre-4.3.9     The pcre shared extension for php

Mathopd and the php software is all installed from ports.

I'm trying to troubleshoot a problem, and want to make sure my
mathopd.conf file isn't causing it.  Currently, if I just use html and
the recommended 'dir_cgi' program, and I use a path (eg -
http://fof.weller-fahy.com/isnthere ) that doesn't exist, I get a 404
message (the URL is real, you can try it).

However, when using wordpress (my website software
http://weller-fahy.com ) and trying the same thing, I always get the
home page of my blog, never a 404.

*Could* this be caused by mathopd?  Or should I be looking at wordpress?
What I'd like is normal 404s no matter which part I'm using, so any help
towards that goal would be wonderful.  If you need any more info don't
hesitate to ask.

Oh, and if I've made an extraordinarily stupid mistake: Please beat me
over the head with it. ;]

## logging picked up by multilog from stderr:
