The little arrows that are in the last post column, that are supposed to take you to the last post of the thread in that column. i.e. these

Well they're not taking me to the last post... instead they're taking me to the site's front page, and by that I don't mean the forum I mean the site itself.

If I click on the linked thread itself in the same column, i.e just above the last posters' name then I get taken to a blank page.

 

Oh the downwards pointing arrows don't work either..
