Sorry about that. It looks like the wiki destroyed itself. I'm not kidding, the damn thing just re-installed itself and erased all the pages I've created.
Note to self: don't use PhpWiki in the feature.
Unfortunately everything (including xslt support) that was made through wiki is gone but most of it is in this article anyway:
