404 page doesn't load right

The number of people online also shows in the sequences pages, as well as on individual user sequences pages, so it shows in at least 2 pages/sections of the site/forum. So yeah, it does not show anywhere in the "forum" area of the website (so it seems).
Basically it shows on the OS main website, but not in any of the OS forum site pages.
