[nelsonmb]

I have some includes of php files in my main page, do i need to put session_start(); in this pages to?

hi!
if you have something like this:

<?php
session_start();
include("file.php");
?>

then there is no need to add session_start() again to file.php

[LarsLai]

yes, on every new page you have to declare session_start()
and by using window.open it is definitely a new one 😉

session_start() has to be in your code before any output.
try to put session_start() in your first row.
