Under normal circumstances the liar is defeated by reality, for which there is no substitute; no matter how large the tissue of falsehood that an experienced liar has to offer, it will never be large enough ... to cover the immensity of factuality.
Fixed misspelling of 'cahce' to 'cache', which was a critical bug that was breaking homepage. Then I removed cache completely. By the way, I haven't audited this code for security. In general, I would highly recommend against running PHP code on a public facing server. It's probably fine to run this (and mediawiki) on your local intranet disconnected from the internet (e.g. put it on a separate VLAN). Because the main use case of a blog is to have it not publicly facing.
