Poster links on download comments: 404

[Maldivia]

When looking at the comments for a download, middle-clicking the name of the poster (to go to their profile page) leads to a 404.

If clicking normally (and JavaScript is enabled in the browser), a drop down menu is shown, and the first menu item leads to:
wowinterface.com/forums/member.php?userid=XXX

But if middle-clicking the link (in Firefox), or right-click and select "open in new window/tab", the link in the href is navigated to directly, which leads to:
wowinterface.com/downloads/member.php?u=XXX
