Blank scoops and no errors.

I run www.nazarene.net

The site had been going along quite nicely for a while, but today when I connected to clear out spam, I found that the scoops are blank on the "all" category for everything but the top365days listing. All other categories seem to display correctly.

I've been trying to look through the database for corruption but haven't found the cause of this as yet. Looking for ideas as there is nothing in apache's error log. and nothing relevant in watchdog.
