ERROR:
Notice: Use of undefined constant VB_SYSTEM_PATH - assumed 'VB_SYSTEM_PATH' in /var/www/vhosts/kunstbewegung.info/httpdocs/wikide7/LocalSettings.php on line 19

LocalSettings.php Line 18-20:
require_once( "$IP/includes/DefaultSettings.php" );
define( VB_SYSTEM_PATH, '/var/www/vhosts/kunstbewegung.info/httpdocs/cde' );
require_once( "$IP/includes/AuthPlugin_vBSSO.php" );

Since I looked around hard and can´t find anybody with the same error, please help.
I did already aply the fix to global.php:

if (!defined('CWD'))
{
define('CWD', (($getcwd = getcwd()) ? $getcwd : '.'));
}

Thank you for helpf
Sincerely yours
