Hallo, I'm getting the following warning on top of all MediaWiki pages: Warning: arg2 must be passed an array in /srv/www/htdocs/wiki/languages/LanguageUtf8.php(53) : regexp code on line 1 It's the MediaWiki version 1.4.0 (the new stable version) on SuSE Linux Enterprise Server 8 with PHP 4.2.2. How can I solve that issue? Regards, Frank
