Warning : session_start(): Cannot send session cache limiter - headers already sent even after using session_start() and ob_start()

Question

I have included Session_start() and ob_start(); in my login page and still getting error Warning:

session_start(): Cannot send session cache limiter - headers already sent (output started at ) on line 3.

I don't know what is the problem.

I tried placing ob_start on first line and on second line same with the Session_start.

Here is my code:

 <?php
session_start();
ob_start();

error_reporting(0);

if(!empty($_SESSION["admin_prince"])){
    header("location:../index.php"); 
}
include '../connection.php';

 ?>

try not using PHP end tags if you're dealing with back-end application logic, this may add white-space which sends content to the browser and hence the headers cannot be modified anymore after any contents has been sent. — , Jul 21 '17 at 11:12
@chris85 yes there is space in php code before session_start() — Prince Arora, Jul 21 '17 at 11:36

I don't know, if your code is well formatted in your question. But if so, remove the blank space before <?php.

Try this

<?php session_start(); ?> 
<?php
ob_start();

error_reporting(0);

if(!empty($_SESSION["admin_prince"])){
    header("location:../index.php"); 
}
include '../connection.php';

 ?>
