satish Platform: GNU/Linux Debian 3.1r1, Apache 2.0.52, PHP 5.2.0-0.dotdeb.3 with Suhosin-Patch 0.9.6.2 Problem: Warning message DokuWiki: dokuwiki-rc2007-05-24.tgz Warning: Warning mb_strrpos() [function.mb-strrpos]: Empty haystack in /usr/share/dokuwiki-rc2007-05-24/inc/pageutils.php on line 155 This warning wasn't there for the previous DokuWiki version. This warning occurs only for the Home page link and not for other pages. Is it a bug in PHP? Can someone tell me what is happening?
