It looks like the sidebox for new articles is using relative links, so on any page deeper than root, it's linking to articles incorrectly. You can see that if you try to click on any of the article links in the sidebox here, for example - Ymirian Glacier, to take a specific link, is pointing to /downloads/products/node/ instead of /entry.php?intEntryID=29625.
Planescape, Dungeons & Dragons, their logos, Wizards of the Coast, and the Wizards of the Coast logo are ©2008, Wizards of the Coast, a subsidiary of Hasbro Inc. and used with permission.
Fixed. Was having an issue with caching the wrong form of the link.
