Cookie for the forums, cookie for non-vB pages, but work together

See, the "Community" section calls on global.php and if you're not logged into the forums (user: Pretty Lush pass: qwerty if you wanna see the working version of that page) gives you the

Unable to add cookies, header already sent.
File: /home/xblgamer/public_html/indexnew.php
Line: 1

So, my thinking is to set a seperate cookie for the forums and a cookie for the main page. The cookie from the main page can be used to get vB info for the community section.

Anyway I can do this? Or is it the wrong solution or what?

EDIT:

Line 1 of the indexnew.php is:
<?php echo "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?".">"; ?>

and if I remove that, it goes down to line 14 or so, which is <style type="text/css"> .

So, it's all odd.
