Warning : session_start(): Cannot send session cache limiter - headers already sent even after using session_start() and ob_start()
I don't know, if your code is well formatted in your question. But if so, remove the blank space before <?php.
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at
The session_start() function should be on top of your file like this:
<?php
session_start(); // Should be on top when using $_SESSION
class Login {
private $db_connection = null;
public $errors = array();
public $messages = array();
public function __construct() {
// Rest of your scripts
This error caused because the headers where sent already so it is to late to load the session_handler() either, that's why you have to put it on top of your file to load it with the headers.
If you use a framework that includes the pages, you only need to use the session_start() once in the main file (e.g. index.php), where you include the other files
I hope this will help you.

I cant comment put all your php codes before <!DOCTYPE html> or in body tags!
Make sure you dont have spaces between <? php tags. where you include files.
Turn on error reporting :
error_reporting(E_ALL);
ini_set('display_errors', 1);
Check error_log file in C:\wamp\logs\php_error.txt if you are using wampserver on localhost.
Try testing for isset($_SESSION) If it already exists then do not use session_start();
Look like you are passing second session start from another file try Like this :
if(!isset($_SESSION)){
session_start();
}
Use session_start() before anything else.
