WordPress MU

Hello,

After upgrading to 2.7.1 wordpress mu, in wp-config I add:
define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

but I found out that after adding that, log out from wp-admin is not log you out from your wordpress template, or home page. How to fix this? Also I experience the same thing on buddypress's adminbar -- log out from admin bar is impossible.

Help please! Thanks...

Go into your wp-config.php and remove the lines that you added because the settings you pasted above are wrong.

So you don't need these lines at all?
