I tink that code is valid except for this:

setcookie("id", 2132421,time()+(60*60*24*5), "/", "");
setcookie("pass", loggedout,time()+(60*60*24*5), "/", "");
echo ("You are now logged out! <br>");
header('Location: index.php');

Try moving the header() to above the echo().
I can't see any real problem with your code there, but I suspect it is to do with the nested if()statements, try using either elseif() statements, or use switch with case statements.

I prefer the latter as it creates what I feel is more readable code, but the choice is yours.

you are right i think its best to replace it with an echo of a html redirect :D i'll let you know what happened

[hyeclass]

it turns out thats not the cause at all. :D
in my index.php i had liek this :
-html
php < my include config was here
-html

-html < shoudl be here include("config.php") or whatever :D
php
-html
