You're only expecting one row to be returned, right? You could test like
this:
if($row = mysql_fetch_array($checkuser))
{
$_SESSION['UN'] = $row['username'];
$_SESSION['UserLoggedIn'] = TRUE;
}
else
{
header("Location: http://yourdomain.com/login.php");
exit();
}
You should use an absolute URI for your header() call, not a relative
one.

Well, Apache 2 and PHP aren't stable together yet. It's not recommended
you use them together and that could be causing your problem.
Are you including this file before or after session_start()? If you call
session_start(), include the above code, and then $_SESSION['UN'] is not
available later in the main.php page, then it's a bug...
