UPDATE 22nd Mar 12: See WordPress 3.x Page Navigation Error with inFocus Theme: Revisited for an updated solution.
These instructions are only applicable for versions of inFocus up to and including v1.6
I hadn’t noticed it, but someone recently pointed out that this site’s page navigation wasn’t working.
I’d upgraded to WordPress 3 a few weeks back and it quickly became clear that this was part if not all of the reason why, as page navigation worked perfectly after downgrading this site to WordPress 2.9.2.
