Upgrading MediaWiki

From SnOwy - Ed's Wiki Notebook

Database can't be read

This results in a bizarre long page of error output instead of the mediawiki main page being displayed. It is likely due to a schema change between versions of mediawiki or an incompatibility with a newer version of mySQL. To fix this, I dropped ALL of the mediawiki data and restored it via a SQL import of the latest export living on another machine-- thanks to backups.

I couldn't get update.php to run correctly as it kept misidentifying my version of PHP as 5.3.1 even though it's 5.3.2, so I ran a fresh config instead.

Wrapping it up

Localsettings.php were then updated with the modifications I like -- the SnOwy logo, no registration, no anonymous editing.
