So im getting a blank page when loading this page within an iFrame on Internet explorer, every other browser works fine..

I have also tried using p3p headers as other people have suggested, but to no avail.

<?php
require ("connect.php");
require ("config.php");
require ("fb_config.php");
?>

  <body>

  <?//=$user?>
  <?php


if($user == 0) {
echo "You are not logged into facebook. Nice try.";
}else{


$query = "SELECT id,fb_id,login_ip,login_count,activated,sitestate FROM login WHERE fb_id='".mysql_real_escape_string($user)."'"; 
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result);

        if (mysql_num_rows($result) == 0) {
    $sql = "INSERT INTO login SET id = '', fb_id ='" .mysql_real_escape_string($user). "', name = '" .rand(10000000000000000,99999999999999999999).

"',activated='2', killprotection = '$twodayprot',gender='" .mysql_real_escape_string($_POST["gender"]). "'";
    $res = mysql_query($sql);
    }


        //if($row['fb_id']  != $user){
        //echo "Your facebook ID: $user is NOT in the MW DB.";
        //exit();
        //}else{


        if(empty($row['login_ip'])){
        $row['login_ip'] = $_SERVER['REMOTE_ADDR'];
        }else{

        $ip_information = explode("-", $row['login_ip']);

        if (in_array($_SERVER['REMOTE_ADDR'], $ip_information)) {   
        $row['login_ip'] = $row['login_ip'];
        }else{  
        $row['login_ip'] = $row['login_ip']."-".$_SERVER['REMOTE_ADDR'];
        }
        }

$update_login = mysql_query("UPDATE login SET login_count=login_count+'1' WHERE name='".mysql_real_escape_string($_POST['username'])."'")
or die(mysql_error());

$_SESSION['user_id'] = $row['id'];

$result = mysql_query("UPDATE login SET userip='".mysql_real_escape_string($_SERVER['REMOTE_ADDR'])."',login_ip='".mysql_real_escape_string($row['login_ip'])."',login_count='0' WHERE id='".mysql_real_escape_string($_SESSION['user_id'])."'")
or die(mysql_error());


if ($row['sitestate'] == 0){
header("location: home.php");
} elseif ($row['sitestate'] == 2) {
header("location: killed.php?id={$row['id']}&encrypted={$row['password']}");
} else {
header("location: banned.php?id={$row['id']}&encrypted={$row['password']}");
}

}// id check.
