The problem is 'Php-type (for Httpd/proxy):' is blank. In this situation, go to 'webserver config' and change to other (let say 'mod_php_ruid2' and then change to 'php-fpm_event'.
Remember, use this 'old' trick (change to other and then back) will be fixed most problem in Kloxo-MR (also Kloxo Official too).
