I bet you have some session management functions in
include('lib/sessionfunc.php');
something like session_start() that also sends out header informations,
but you can't send any headers AFTER you have started
the output for eg:
<?
.... some cookies/session/header code1
?>
Some HTML output like:
<html>
<head>
<?
.... some cookies/session/header code2
?>
code1 will work ok, but code2 will fail with headers already sent error.
Instead you should write :
<?
ALL cookies/session/header code
?>
The HTML code
<?
other PHP code
?>
the headers are sent before any HTML code, so if you have even one
blank space sent to the output you can't modify the headers any more.
