Set correctly error reporting and see the Warnings.

You can't start session or redirect using header when there is any output before, move session_start to the top of PHP script.

index.php

<?php include('header.php'); ?>
<?php include('navbar.php'); ?>
<?php

session_start();

if (isset($_POST['submit'])) {
    // all PHP code goes here
}

?>

HTML goes here
