I have this at the very top of my send.php file:
send.php
ob_start(); @session_start(); //some display stuff $_SESSION[\'id\'] = $id; //$id has a value
Go to your PHP.ini file or find PHP.ini EZConfig on your Cpanel and set your session.save_path to the full path leading to the tmp file, i.e: /home/cpanelusername/tmp
PHP.ini
PHP.ini EZConfig
Cpanel
session.save_path
tmp
/home/cpanelusername/tmp
