WordPress MU

Hello there,
I've opened a new WPMU test site (www.querg.com)and then I tried to install a regular wordpress blog in a folder which sits inside the root folder where my installation of WPMU sits (www.uriashi.com - which is actualy "querg.com/uriashi").
I've tried installing it many times but to no avail - everytime the blog itself is installed succesfully but when I try to reach the admin panel it outputs those lines of errors:

Warning: Cannot modify header information - headers already sent by (output started at /home/quergcom/public_html/uriashi/wp-config.php:1) in /home/quergcom/public_html/uriashi/wp-login.php on line 9

does anyone has a clue as for what's going on here?
thanks,

I'm lost though. You're putting a regular wordpress install within a wpmu install and doing is as a domain redirect? Why not just setup a seperate account or just do domain mapping and put it within your wpmu install?

Hi drmike,
I thought about this solution but I plan to limit the options in the WPMU blog and in my regular blog I want all the options available.

i solved this problem
use this code
<?
//dont use header function in wordpress-wp_signup.php
global $domain;
global $path;
//change urlnew variable as per requirment
$urlnew = "http://".$domain.$path."/wp-admin/admin.php;

echo "<script>";
echo "location = '$urlnew';";
echo "</script>";
echo $urlnew;
?>
