Session warning messages

[Anon]

Anyone know what this means?

Warning: Cannot send session cache limiter - headers already sent in ../includes/admin_header.php3 on line 2

And why would it suddenly appear on only a couple of pages which are almost identical to others that are working fine?

code is:

<?php
session_start();
if (!$PHPSESSID)
{
session_register('bg');
session_register('navdir');
$bg = "#ffcc33";
$navdir = "10";
}

require "../includes/functions.php3";
include("../includes/bg.php3");
?>

All this is in an include file wihich is included at the top of every page, which works great except for a couple of pages?

It means that you have printed some text (can be a single character or linebreak)
at line 2 or "admin_header.php3"

Just like any header, the session_start() must be sent before any text is printed.

gees you were right....it was as simple as starting the code from the very top of the page as opposed it starting on the second line which would indicate a space.

cheers.
