Upgrade 1.9.3 -> 1.12.0 fails

We successfully run mediawiki for a year with version 1.9.3
(with an extension function defining these hooks:
AutoAuthenticate, SpecialPage_initList, UserLogoutComplete).

Now we tried to upgrade to 1.12.0. The upgrade process seemed
to be OK, since the installer completed with "Installation
successfull".
However, it does not work; the error log states:
PHP Fatal error: Class 'DOMDocument' not found in
/magwien/var/gondor-phpserver/html/m13wiki/includes/Preprocess
or_DOM.php on line 566

Best regards

Are you using FreeBSD, perchance? If so, you'll probably need php5-dom
or php5-extensions - see
http://www.gossamer-threads.com/lists/wiki/mediawiki/128445 .

HTH. :)

This is a bug in MediaWiki, and could easily be fixed by backporting
r34283 and releasing 1.12.1.

the problem is related specificaly to v1.12.0

There is a quick fix - add to LocalSettings.php:
$wgParserConf['preprocessorClass'] = 'Preprocessor_Hash';

The "permanent" fix is to install the 'php-xml' package and restart Apache:
# yum -y install php-xml (on fedora anyway)
# service httpd restart

Actually, I found the "permanent" fix was quicker to implement than the
quick fix 8^) ...but I tested each and both worked (for me)

the reference is (watch out for the line wrapping):
