Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site2/fst/var/www/html/cp/edit_member.php:1) in /home/virtual/site2/fst/var/www/html/cp/common.php on line 3

i keep getting this error above... what does it mean by header already sent??

 <? include("http://www.69kilobytes.co.uk/header.php"); ?>
 <? 
include_once("common.php");
include 'connect.php'; 

$table_name = 'members'; 
$entry_id = 'username'; 

if(array_key_exists('EditIt', $_POST) && !empty($_POST['EditIt'])){  

   $fieldst = 'SET '; 
   $increment = 0;

    What that means is that information was already sent to the browser. You probably have a space before the opening PHP tag.

    Try replacing the top part of your code with this:

    <?php

include("http://www.69kilobytes.co.uk/header.php");

include_once("common.php");
include ('connect.php');

      How about posting the contents of common.php, since that appears to be where the attempt to send headers is coming from... (Do you have a header() somewhere in that file?)

        I would simply recommend output buffering...

        [man]ob_start[/man]

        as it seems you have multiple files with multiple header files.... (which gets ugly without buffering)
