Advanced Poll 2.0.2 error:Warning: Cannot modify header info

Hi all and TNX for any help.

I try to install a poll for my web page and I find this one.

Is a really good poll with easy installation, the poll works but sometime I get this error:

Warning: Cannot modify header information - headers already sent by (output started at /u/web/sfane1/test/news/en.php:2) in /u/web/sfane1/poll/poll_cookie.php on line 21

This error it appears at the top of the web page.

In the head of my web page I have this:

<?php
// Important! You have to include it before your html code
include_once "/u/web/sfane1/poll/poll_cookie.php";
?>
<html>
<head>

I put this as the setup of the poll explain.

and this is the poll code in the web page:

<?php
include_once "/u/web/sfane1/poll/booth.php";
echo $php_poll->poll_process(4);
?>

You simply needed to put the REAL PATH to your cookie file like this:

Code:
<?php
/* Include this before your html code */
include "/usr/home/warzoneonline/public_html/poll/poll_cookie.php";
?>

Sorry that all these other people are giving you funky advice.
