Might also try the MagicNoCache extension
(
http://www.mediawiki.org/wiki/Extension:MagicNoCache). This extension creates a magic
word (__NOCACHE__) that disables the cache for that page.

Purging doesn't cause any changes: it just forces the system to
regenerate some things.[0] I think it's normal for categories to
exhibit this "sticky" behavior, and the job queue might also be
involved (but I might be misremembering and making the whole thing
up).
