Dear,
I got this fatal error
Fatal error: Call to undefined function mb_strtolower() in /var/www/mediawiki1.20.4/extensions/PslZendSearchLucene/PslZendSearchLucene_body.php on line 975.
I check that fine, it's mb_strtolower($wgRequest ->getText('category'));
anyone got this problem before?
Any help is welcome, thanks in advance.
