I was having some odd problems with my WDW 06 category, where it wouldn’t actually come up with any content when I went to it. Not all the archives were doing that, just a couple.
I spent an inordinate amount of time trying to track down the problem as though it were a SmartyPants pagination hack problem; eventually I did a test category archive template without the SmartyPants stuff, and was still having the same problem.
I then spent a while looking at all the entries in the category (via the MT Entries screen, filtered), but didn’t see anything odd.
I then discovered that the May 2006 monthly archive wasn’t loading, which would still indicate it was a problem with one of the WDW entries, or …
Hrm.
Changed the number to display per SmartyPantsed archive page to only 10 (from 30) and, hey presto, it works.
I suspect it’s the large number of pictures and divs, but, regardless, normal functionality has resumed.
