Cookie deletion problem

[geniusgoalie]

I'm having a bit of a problem with deleting a cookie. I have this code:

if ($_GET['logout'] == "true")
{
    $_SESSION = array();
    session_destroy();
    setcookie("loggedin", "TRUE", time()-(3600 * 24));//the line with the problems
} 

for some reason, it is giving a "headers already sent" error. What is wrong?

Any spaces before this code block?

Yes, it goes like this:

<?php
include('common.php');
include('config.php');
include('prefs.php');

$dir = $_GET['dir'];
$dirsize = dirsize("{$rootpath}{$username}");
$trueuser = str_replace($rootpath, '', $dir);

if ($_GET['logout'] == "true")
{
    $_SESSION = array();
    session_destroy();
    setcookie("loggedin", "TRUE", time()-(3600 * 24)); //EEEEVIL!!!

I meant spaces before the

<?php

Any possibility your includes do some output? Any error messages popping up?

HEre is the error:

Warning: Cannot modify header information - headers already sent by (output started at /home/me/public_html/common.php:6) in /home/me/public_html/viewfiles.php on line 14
Logout failed- cookies were not cleared!
You will be redirected to your user control panel in three seconds.
If the problem persists, please contact the webmaster.

(The last three lines were the die code)
And there are no spaces before the <?php

These are the top six lines in the common.php page though... it makes no sense

<?php
session_start();
header("Cache-control: private");
include('config.php');
include('prefs.php');
echo "<LINK REL=\"stylesheet\" TYPE=\"text/css\" HREF=\"style.css\">";

The "echo" my friend, the "echo"

This is the actual output.
