Hi, I just upgraded from MediaWiki 1.13 to 1.15. I also upgraded the extension ParserFunctions which I updated directly from SVN to the last version: $ svn info Path: . URL: http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/ParserFunctions Repository Root: http://svn.wikimedia.org/svnroot/mediawiki Repository UUID: dd0e9695-b195-4be7-bd10-2dea1a65a6b6 Revision: 53274 Node Kind: directory Schedule: normal Last Changed Author: siebrand Last Changed Rev: 52757 Last Changed Date: 2009-07-04 01:41:53 +0200 (Sat, 04 Jul 2009) $ svn update U Expr.php U ParserFunctions.i18n.magic.php U ParserFunctions_body.php U ParserFunctions.i18n.php U ParserFunctions.php U funcsParserTests.txt Updated to revision 67914. Now I get the following error when I go to my Mediawiki: Magic word 'if' not found Backtrace: #0 /usr/local/share/mediawiki/includes/MagicWord.php(244): Language->getMagic(Object(MagicWord)) #1 /usr/local/share/mediawiki/includes/MagicWord.php(197): MagicWord->load('if') #2 /usr/local/share/mediawiki/includes/parser/Parser.php(4034): MagicWord::get('if') #3 /usr/local/share/mediawiki/extensions/ParserFunctions/ParserFunctions.php(72): Parser->setFunctionHook('if', Array, 2) #4 [internal function]: ParserFunctions_HookStub->registerParser(Object(Parser)) #5 /usr/local/share/mediawiki/includes/Hooks.php(117): call_user_func_array(Array, Array) #6 /usr/local/share/mediawiki/includes/parser/Parser.php(178): wfRunHooks('ParserFirstCall...', Array) #7 /usr/local/share/mediawiki/includes/parser/Parser.php(190): Parser->firstCallInit() #8 /usr/local/share/mediawiki/includes/parser/Parser.php(312): Parser->clearState() #9 /usr/local/share/mediawiki/includes/Article.php(3557): Parser->parse('{{Box?|Headline...', Object(Title), Object(ParserOptions), true, true, 10103) #10 /usr/local/share/mediawiki/includes/Article.php(979): Article->outputWikiText('{{Box?|Headline...') #11 /usr/local/share/mediawiki/includes/Wiki.php(450): Article->view() #12 /usr/local/share/mediawiki/includes/Wiki.php(63): MediaWiki->performAction(Object(OutputPage), Object(Article), Object(Title), Object(User), Object(WebRequest)) #13 /usr/local/share/mediawiki/index.php(116): MediaWiki->initialize(Object(Title), Object(Article), Object(OutputPage), Object(User), Object(WebRequest)) #14 {main} Does anybody know how I could resolve this?
