User pages not linking correctly?

[Elusive]

Clicking on anyone's username - which would usually bring me to their control panel so I can leave messages, send PMs and such - resolves to a 404 Not Found error.

You know the 'Active Users' list at the bottom of the front page?

Clicking my name takes me to http://www.sega-16.com/forum/26, which results in the 404.

I'm unable to view anyone's profile at all. What gives?

Try restarting your computer, because it seems to be working fine for me.

Clicking it in a post seems to work, perhaps the forum is giving bad URLs? (http://www.sega-16.com/forum/member.php?u=26)
