logging out with cookies

[pneudralics]

Everytime I logout and go to the url and type in localhost/logout.php I else statement which I shouldn't get unless I just logged out. I can type in localhost/logout.php all day and it'll show my else statement.

 

But if I refresh the page I'll finally get my error.php. How do I fix it so after I logout and I type in localhost/logout.php it'll show the error page instead of showing that I just logged out.

 

The below is my logout.php

<?php
ob_start();
if(!isset($_COOKIE['id']) && !isset($_COOKIE['idsession']) && !isset($_COOKIE['ip'])){
include ('c/connect.php');
include ('header.php');	
include ('sideleft.php');
?>
<div id="maincolumn">
<?php
require ("error.php");
?>
</div>
<?php    
include ('footer.php');	 
} else { 
include ('c/connect.php');
include ('header.php');
setcookie('id', '');
setcookie('id', '', time() -3600);
setcookie('idsession', '');
setcookie('idsession', '', time() -3600);
setcookie('ip', '');
setcookie('ip', '', time() -3600);
ob_flush();
?>
<?php
include ('sideleft.php');
?>

<div id="maincolumn">
<div class="text">
You have successfully logged out of HappyProfile.com
<br />
Thanks for visiting and come back soon!
<br />
<a href="login.php" style="font-weight:bold;">Log Back In</a>
</div>
</div>
<?php
include ('footer.php');
}//End session else
?>

Get rid of ob_start() and ob_flush(), it's completely unnecessary on a script of that size.
