MyBB Community Forums

I am integrating mybb in website.
I can login, logout now. But if i logined via forum, I can not logout in website. Just cannot change 'mybbuser' cookies set by forum.

setcookie('mybbuser', '', -3600, '/');	

Just does not working.

And vice versa, if I login in website

setcookie('mybbuser', $uid.'_'.$loginkey, time()+2419200, '/');

Then i can use forum, but cannot logout in forum, only in site.


How can I edit mybbuser cookie by php's setcookie()?

I found it. It is domain of setcookie() that should be equal to mybb configuration's domain.
