It's probably caused by the whitespace before opening PHP tag.

Please Check the Home.php page: Probable Problems are:

1.If something is echoed above header('location:XXXXX');

2.If you have some empty lines above header('location:XXXX');

Check it and Try Removing these things.

Try this, Removed white space before PHP tag

 <?php
    //Start session
    session_start();
    //Check whether the session variable SESS_MEMBER_ID is present or not
    if (!isset($_SESSION['id']) || ($_SESSION['id'] =='')) {
        header("location: /index.php");
        exit();
    }
    $session_id=$_SESSION['id'];
    $user_query = $conn->query("select * from members where member_id = '$session_id'");
    $user_row = $user_query->fetch();
    $name = $user_row['firstname']." ".$user_row['middlename']." ".$user_row['lastname'];
    ?>

if you are including this file in other file then make sure you don't echo anything or use ob_start() as first line of your code. Hope this will help.

Most probably the problem is due to the white spaces above your link. Try removing those white spaces
