Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Program Files\Software602\602LAN SUITE\DOCS\PHP\db_fns.php:14) in C:\Program Files\Software602\602LAN SUITE\DOCS\PHP\index.php on line 3

<?php
  include ('include_fns.php');
  session_start();

  // check if we have created our session variable
  if(!isset($HTTP_SESSION_VARS['expanded']))
  {
    $HTTP_SESSION_VARS['expanded'] = array();
  }

  // check if an expand button was pressed  
  // expand might equal 'all' or a postid or not be set
  if(isset($HTTP_GET_VARS['expand']))
  {
    if($HTTP_GET_VARS['expand'] == 'all')
      expand_all($HTTP_SESSION_VARS['expanded']);
    else
      $HTTP_SESSION_VARS['expanded'][$HTTP_GET_VARS['expand']] = true;
  }
 
  // check if a collapse button was pressed  
  // collapse might equal all or a postid or not be set
  if(isset($HTTP_GET_VARS['collapse']))
  {
    if($HTTP_GET_VARS['collapse']=='all')
      $HTTP_SESSION_VARS['expanded'] = array();
    else
      unset($HTTP_SESSION_VARS['expanded'][$HTTP_GET_VARS['collapse']]);
  }

  do_html_header('Discussion Posts');

  display_index_toolbar();

  // display the tree view of conversations

just put the  session_start(); first in the page and it should solve your problem. The session must b einitiated before anything else.

you can put includes before session_start()
but those includes cannot output anything!
now i have had this problem before and it was simply caused by the include class
having a space after the closing ?> tag so make sure there is no spaces before or after the php tags.
