I read the answers here How to fix "Headers already sent" error in PHP but this not fix my error.
i don't understand, session_start() is the first thing i call in my files and I am using the UTF-8 without BOM encoding. But i still get this php warning.
Error :
PHP Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/feyzprod/public_html/nearby/register.php:1) in /home/feyzprod/public_html/nearby/register.php on line 1
My file encoding is
Encoding is UTF-8 without BOM
Code :
<?php session_start();
require_once('bdservice.php');
require_once('script.php');
$bd = new BDService();
?>

You probably have a space or other whitespace character at the beginning of /home/feyzprod/public_html/nearby/register.php, indicated in your error that it is on line 1.
The space will echo to the output which means that you can no longer write to the headers, which is where PHP wants to set the session information via a cookie.
