address to a page with php

I am making a form that when sending the data by mail if they are sent successfully I return to the home page but doing so gives me the following error:

  

Deprecated: preg_replace (): The / e modifier is deprecated, use preg_replace_callback instead in /var/www/new_arreglosya/class.phpmailer.php on line 1918

I'm working with PHP and the PHPMailer class, it should be noted that the email arrives perfectly to the email address but does not direct me to the homepage.

This is the code I use to redirect:

$data = enviar_correo($nombre, $direccion, $celular, $correo, $servicio, $precio);
if($data){
    header("Location: http://localhost/new_arreglosya/");
} else {
    echo "No enviado";
}
