"404 not found" from CUPS-Server

[Zö Ti]

Everytime I connect to localhost:631 I get a website telling me "404 not found".
I tried two different browsers (firefox and links)(, as well as accessing from another PC (via IE). This time it gives me a "403 permission denied", just fyi).
Trying to install a printer using kcontrol results in this one hanging up while waiting for the cupsd. Shutting /etc/init.d/cupsd stop while the programm is waiting gives an error and the control center resumes running.

Here the access_log of one connection attempt:
localhost - - [03/Sep/2007:22:47:54 +0200] "GET / HTTP/1.1" 404 0 - -
localhost - - [03/Sep/2007:22:47:54 +0200] "GET /cups.css HTTP/1.1" 404 0 - -
localhost - - [03/Sep/2007:22:47:54 +0200] "GET /favicon.ico HTTP/1.1" 404 0 - -


and the according error_log:
