Check to see if the user is logged in error

[cmb]

on all my secured pages at the the very top the code is

<?php
require ("u_check_login.php");
?>

and then the u_check_login.php code is

<?php
require('database.php'); //Include DB connection information
$ip = mysql_real_escape_string($_SERVER["REMOTE_ADDR"]); //Get user's IP Address
$email = mysql_real_escape_string($_COOKIE['uemail']); //Get username stored in cookie
$pp = mysql_real_escape_string($_COOKIE['pp']);
if ($pp == 1){
$sessionid = mysql_real_escape_string($_COOKIE['sessionid']); //Get user's session ID
$check = mysql_query("SELECT * FROM `users` WHERE `email` = '$email' AND `session_id` = '$sessionid' AND `login_ip` = '$ip' AND `pp` = '1' ") or die(mysql_error()); //Check if all information provided from the user is valid by checking in the DB
$answer = mysql_num_rows($check); //Return number of results found. Equal to 0 if not logged in or 1 if logged in.
if ($answer == 0 || $sessionid == '') { //Check if login is valid. If not redirect user to login page
header('Location: ulogin.php');
exit();
}
$row = mysql_fetch_array($check);
$email = stripslashes($row['email']);
}else{
header('Location: ulogin.php');
}
?>

and this error is being displayed on my page that is supposed to not have let me on because i was not logged in

No i saw it, it didn't help me at all, i already new that you cant have anything output before a header but i don't and that's why I'm confused as to why its not working

but i don't

 

But you do - output started at /home/content/03/8587103/html/pinkpanthers/pinkpanthers.php:1 (line 1), otherwise that error would not be occurring.

 

You either have something in your file on line one, before the <?php tag or like that sticky post states, you have BOM (Byte Order Mark) characters as part of the file and they are being output.
