Our intranet wiki is MediaWiki 1.11. Someone did something unknown to it and a pile of stuff doesn't work (JPEG upload, for instance - see previous messages on this topic). I tried an upgrade to the latest stable version and it failed! Clearly, something is deeply messed up. It should be possible to take a database dump, undump to a fresh copy and rebuild the config with our desired options. (Config will now be kept in local svn for recoverability!) Then I should be able to upgrade to latest stable. Questions: 1. Has anyone else done this? Gotchas? 2. If the fouled-up-ness extends to the data in the database, such that the reinstalled copy is broken in the same way ... what partial recovers are possible? - d.
