suPHP错误:不在配置的docroot中

On my Ubuntu server 14.04 I've changed the Apache document root thanks to a symbolic link. I firstly renamed the original /var/www directory to /var/www-old than I created a symbolic link to the new document root: sudo ln -s /srv/datadisk01 /var/www

Everything seems fine except I cannot run any PHP scripts as I get a 500 error.

suphp.log says: Script "/var/www/website/html/phpinfo.php" resolving to "/srv/datadisk01/website/html/phpinfo.php" not within configured docroot

So I've changed some parameters in /etc/susphp/suphp.conf

Adding the path to the new document root docroot=/var/www:/srv/diskdata01:${HOME}/public_html

turning check vhost to false check_vhost_docroot=false

but suphp.log is keep saying Script "/var/www/website/html/phpinfo.php" resolving to "/srv/datadisk01/website/html/phpinfo.php" not within configured docroot

I really run out of solution. Can someone please helps me ?

Thanks
