Step 3.

In class_core.php ;

Find ;

// define session constants
define('SESSION_IDHASH', md5($_SERVER['HTTP_USER_AGENT'] . vB_Session::fetch_substr_ip($registry->alt_ip))); // this should *never* change during a session
define('SESSION_HOST', substr($registry->ipaddress, 0, 15));

Replace with ;

// Paul M - Define session constants
define('SESSION_HOST', substr(IPADDRESS, 0, 15));
define('SESSION_IDHASH', md5($_SERVER['HTTP_USER_AGENT'] . vB_Session::fetch_substr_ip(IPADDRESS)));

Mine with 3.64 is differnet ..

// define session constants
define('SESSION_HOST', substr($registry->ipaddress, 0, 15));

if (!defined('SESSION_IDHASH'))
{
define('SESSION_IDHASH', md5($_SERVER['HTTP_USER_AGENT'] . $this->fetch_substr_ip($registry->alt_ip))); // this should *never* change during a session
}

What I'm trying to say is that my code is not the same , the last two are not in the same location .. Total
