No puedes tener ningun espacio en blanco delante de session_start(); Sorry for my english: you cant have any blank spaccing before SESSION_START() Prueba: TRY: <?php session_start(); echo 'Welcome to page #1'; $_SESSION['favcolor'] = 'green'; $_SESSION['animal'] = 'cat'; $_SESSION['time'] = time(); // Works if session cookie was accepted echo '<br /><a href="page2.php">page 2</a>'; // Or maybe pass along the session id, if needed echo '<br /><a href="page2.php?' . SID . '">page 2</a>'; ?>
