Hello,

When I go to a survey I always receive this message, why and what can I do?

Warning: preg_match_all() [function.preg-match-all]: Compilation failed: unrecognized character after (?< at offset 3 in /var/www/vhosts/mydomain.nl/httpdocs/components/com_cjlib/framework/functions.php on line 2455

Thanks
