Hi,
after upgrading from 1.11 to 1.12 on FreeBSD6.3 I get the error message above. I found a solution here: http://www.mediawiki.org/wiki/Project:Support_desk#.28RESOLVED.29_PHP_Fatal_... $wgParserConf['preprocessorClass'] = 'Preprocessor_Hash';
I just would like to know if this is a confirmed bug or rather a "local problem". php-xml is installed.
Thanks, Helmut
