Warning message

Hi.

When I do any change on my site, like updating a page or whatever I get to a white page with this message:

Warning: Cannot modify header information - headers already sent by (output started at /home/marteens/public_html/wp-content/themes/rumput-hijau/functions.php:32) in /home/marteens/public_html/wp-includes/pluggable.php on line 876

I tried to see what was on the line 876 in the …/pluggable.php, and I found this:

function wp_redirect($location, $status = 302) {
	global $is_IIS;

	$location = apply_filters('wp_redirect', $location, $status);
	$status = apply_filters('wp_redirect_status', $status, $location);

	if ( !$location ) // allows the wp_redirect filter to cancel a redirect
		return false;

	$location = wp_sanitize_redirect($location);

	if ( !$is_IIS && php_sapi_name() != 'cgi-fcgi' )

(line 876)		status_header($status); // This causes problems on IIS and some FastCGI setups

header("Location: $location", true, $status);
}
endif;

I use the Rumput Hijau theme.

What can I do?
