I had problems with logging out in firefox, i tried all stuff like cleaning cookies, check the settings, clean cache but it kept nagging me.
So i went to investigate the login / logout file.
What i noticed was :
When a user logs in, these 2 lines in members.php are run
my_setcookie("mybbuser", $user['uid']."_".$user['loginkey'], null, true);
my_setcookie("sid", $session->sid, -1, true);
now what i did was changed the true state of both into a false state like
my_setcookie("mybbuser", $user['uid']."_".$user['loginkey'], null, false);
my_setcookie("sid", $session->sid, -1, false);
and voila, my problems regarding to firefox where solved, some research towards the my_setcookie function gave me this info
my_setcookie
void my_setcookie( string $name, [string $value = ""], [int $expires = ""], [boolean $httponly =
false])
[line 1483]
MyBB setcookie() wrapper.
Parameters
* string $name - The cookie identifier.
* string $value - The cookie value.
* int $expires - The timestamp of the expiry date.
* boolean $httponly - True if setting a HttpOnly cookie (supported by IE, Opera 9, Konqueror)
Maybe someone has something on this info to solve their problems
at least my forums work fine now on both IE8 + FF 3.6 i can logout without staying logged in !
