My b2evolution Version: 2.x

In this blog
http://mattandcat.co.uk/reviews/
any multiple pages I use don't go to the next page on the list, they re-order the posts by number of views. This seems to happen throughout the blog. It means you can never really find anything further than the first page.

I've poked around (found this http://forums.b2evolution.net/viewtopic.php?t=15580 ) but don't really know where to start looking for this one. Any ideas?
