Argh php help?

Hey guys, I keep getting this STUPID error, it may be something totally obvious or the fact I haven't stopped coding for the past few days and getting tired :P

Basically I'm building a CMS and when the user logs in I want it to display "Hi $username welcome to the panel!';

So I create a welcome.php file and use a php include in the box I want it to display the text but it displays it but I get a stupid cache error :S

PHP Code:

---

Warning:  session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/igoboy/public_html/cms/userpanel.php:6) in /home/igoboy/public_html/cms/welcome.php on line 9
Hi lucas, welcome to your panel! You have 0 new messages since you last logged in!

Any ideas guys? Also I've checked the code and it looks fine.

Moved by jesus (Forum Super Moderator) from Designing & Development: Please post in the correct section next time.

You have session_start(); on an included page and the page you are including on.

Nope, I've only included the file into the userpanel, haven't started any sessions.

PHP Code:

---

<div id="box"><?php include("welcome.php"); ?></div>

Thats the only php I have in my userpanel atm (started a new one)

I do believe sessions cannot be initialized after html is outputted. Not completely sure though.

This is correct, initialize them at the top of the page before any HTML.

Ahh crap, thanks anyway :)
I can just put it in the userpanel.php file but when I do that php has to be at the top, and it displays "Welcome lucas" at the top of the page rofl.

@Lolcopters - Yeah I put the whole of welcome.php at the top of the page before inserting html but then it just went to the top so I thought ohh.. php include :P
