headers already sent by

Hi

I am just setting up a new install of wordpress 2.3.2. I have chosen the theme Beautiful Sunrise 1.2 by Mark Breuer. The only moderations I have made are a new logo and change the fonts.

For some reason when I try to make a post, I get the following error:

Warning: Cannot modify header information – headers already sent by (output started at /home/tester/public_html/wp-content/themes/bs10/functions.php:72) in /home/tester/public_html/wp-includes/pluggable.php on line 391

Line 391 of pluggable.php reads header(“Location: $location”);

Line 72 of functions.php reads:

<?php

define(‘HEADER_TEXTCOLOR’, ”);
define(‘HEADER_IMAGE’, ‘%s/images/beautiful-sunrise.jpg’);
define(‘HEADER_IMAGE_WIDTH’, 850);
define(‘HEADER_IMAGE_HEIGHT’, 200);
define( ‘NO_HEADER_TEXT’, true );

function admin_header_style() {
?>

I would really appreciate some help

Thanks
