Ooops – please see my conversation with Donncha in the ticket above.

The short story: defining COOOKIEHASH as md5(get_option(‘site_url’)) will work for the main blog but not any other blogs if you are using VHOST (subdomains).

There is a fix/hack: calculate the md5 hash of your domain, and use that value to define COOKIEHASH.

define('COOKIEHASH', md5('http://yourdomain.com');

No subdomains, no trailing slashes, will work fine.

You can also get this value from bbPress speedup settings, found at Settings, WordPress Integration, and the bottom of the page.

$bb->authcookie = 'wordpress_biglonghashvalue';

$bb->secure_auth_cookie = 'wordpress_sec_biglonghashvalue';

$bb->logged_in_cookie = 'wordpress_logged_in_biglonghashvalue';

In your wp-settings.php,

define('COOKIEHASH', 'biglonghashvalue');
