Pages still in with PR but no Description or Title!

4000+ pages all retaining their PR but no Desc nor Title

[super_seo]

I dont know whats happened, but sometime around the 21st of Oct. the titles and descriptions for 4000+ (all) of my pages just disappeared along with of course my positions! The PR for the time being is holding strong but what the hell could be going on here. Spiders havent been by for more than 2 weeks now.

Help please
suggestions?
