What's wrong with my sessions?
Question
When i try to go to the home page, the page becomes blank and it is because of the session tags because when i remove them the page shows.
Home page:
<?php
session_start();
include 'includes/db_connect.php';
if(!isset($_SESSION['LoggedIn']) && !isset($_SESSION['Username']))
{
header('Location:home.php');
?>
<!DOCTYPE html>
<html>
<head>
<title>Home</title>
<link rel="stylesheet" href="styles/home.css" type="text/css" >
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel="stylesheet">
<script type="text/javascript" src="js/nav.js" ></script>
<script type="text/javascript">
<!--
function toggle_visibility() {
var e = document.getElementById("nav");
if(e.style.display == 'table')
e.style.display = 'none';
else
e.style.display = 'table';
}
//-->
</script>
</head>
<body>
<div class="Menu" >

This is my login page where the session is stored:
<?php
session_start();
include 'includes/db_connect.php';
?>
<html>
<head>
<title>Howlers | Login</title>
</head>
<body>
<div class="login" >
<?php
if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['Username']))
{
header('Location=home.php');
?>
<?php
}
elseif(!empty($_POST['username']) && !empty($_POST['password']))
{
$username = mysqli::real_escape_string($_POST['username']);
$password = md5(mysqli::real_escape_string($_POST['password']));
$checklogin = mysqli::query("SELECT * FROM users WHERE Username = '".$username."' AND Password = '".$password."'");
if(mysqli::num_rows($checklogin) == 1)
{
$row = mysqli::fetch_array($checklogin);
$email = $row['Email'];
$_SESSION['Username'] = $username;
$_SESSION['Email'] = $email;
$_SESSION['LoggedIn'] = 1;
header('Location=home.php');
}
else
{
echo "<h1>Error</h1>";
echo "<p>Sorry, your account could not be found. Please <a href='login.php'>click here to try again</a>.</p>";
}
}
else
{
?>

one of error is the redirect in the login-page:
you write header('Location=home.php');
The equal is wrong, use the double-point: header('Location:home.php');

You didn't close the if condition proper in home page:
if(!isset($_SESSION['LoggedIn']) && !isset($_SESSION['Username']))
{
header('Location:home.php');
}
you forgot to close the if condition which was fatal error!

Make following changes in your pages
Home Page
<?php
session_start();
include 'includes/db_connect.php';
if(!isset($_SESSION['LoggedIn']) && !isset($_SESSION['Username']))
{
header('Location:home.php');
}
?> ...
Login Page
...
<?php
if(!empty($_SESSION['LoggedIn']) && !empty($_SESSION['Username']))
{
header('Location:home.php');
?>
<?php
}
?>
...
and
...
if(mysqli::num_rows($checklogin) == 1)
{
$row = mysqli::fetch_array($checklogin);
$email = $row['Email'];
$_SESSION['Username'] = $username;
$_SESSION['Email'] = $email;
$_SESSION['LoggedIn'] = 1;
header('Location:home.php');
}
...
