CakePHP Plesk Open Base Dir problem

I've created http://spot.timeoutkl.com to test my Cake PHP 1.2 installation and the default CakePHP page gives me openbase dir error.

What I did was

1.Edit file and then restart back webservice

[root@localhost spot]# cd conf/
[root@localhost conf]# ls
[root@localhost conf]# cd ..
[root@localhost spot]# cd conf/
[root@localhost conf]# vi vhost.conf
[root@localhost conf]# pwd
/var/www/vhosts/timeoutkl.com/subdomains/spot/conf
[root@localhost conf]# vi vhost.conf
[root@localhost conf]# /usr/local/psa/admin/sbin/websrvmng -v -a
[root@localhost conf]#

What's is inside vhost.conf ?

php_admin_value open_basedir none
