-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I just tried upgrading from 1.19.2 to 1.20.0. I followed the standard procedure of backing up my DB, extracting the tarball to a new directory, copying over my images, LocalSettings.php, and one custom extension, and running maintenance/upgrade.php. I run a pretty much "vanilla" wiki with one very basic custom extension (which blocks and logs spammers based on block lists) and a custom skin derived from MonoBook. Everything seemed to be going fine until I attempted to access the main page. I then got a "Fatal exception of type MWException" on an otherwise blank page (500 HTTP error). I went to the "how to debug" page in the Manual (https://www.mediawiki.org/wiki/Debug) and tried turning PHP error reporting with no luck. I turned on the debug log file, with the output inlined below. I'm no MediaWiki hacker by any means, but from what it looks like the "MagicWord" parser is blowing up on an "invalid magic word" on my main page ("speciale"). That token doesn't look familiar to me, and I have no idea if it actually exists in my main page since I can't exactly look at it at the moment. I'm not familiar enough with the back-end tables to know what to query from where. For now I'm backing out all my changes and falling back to 1.19.2. I'm the only one with write access to my wiki, but I can't afford the downtime for my readers. I can't seem to get anywhere with this, no matter what I tweak. Any ideas?
