error after login (PHPBB integrated with cpg)

[setth]

after installing phpbb forum and cpg, and modifying the files and creating the cpg_redir.php file (see below) im getting the folowwing error:


Warning: Cannot modify header information - headers already sent by (output started at /''/''/''/''/phpbb/cpg_redir.php:2) in /''/''/''/''/phpbb/cpg_redir.php on line 9

wat does this error mean?


cpg_redir.php file<?php

if (!$_SERVER['HTTP_HOST']) {
  $cpg_host=$HTTP_SERVER_VARS['HTTP_HOST'];
} else {
  $cpg_host=$_SERVER['HTTP_HOST'];
}
$cpg_path='/cpg/';

exit;
