FlamingGrapeZ, "Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at bla bla bla..." means that you tried to set a cookie before the output started.
What does this mean?
You did something like this:
<html>
<head>
<?php
*you set a cookie here*
?>
*rest of the page*
How it should be:
<?php
*you set a cookie here*
?>
<html>
<head>
and so on...
Just make sure you set cookies (and sessions) BEFORE any HTML, CSS, JavaScript... and other languages
It's not that he set a cookie there, it's that he put the session_start() function AFTER the <html> tag, which is what I had explained to him at PlazaCommunity5.
