 * I’m receiving an error message:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/izacacom/public_html/blog/wp-content/themes/Izaca_blog/functions.php:
   11) in /home/izacacom/public_html/blog/wp-includes/pluggable.php on line 39
 * …when I go to my blog with the www in the url ([http://www.izaca.com/blog](http://www.izaca.com/blog)),
   but it works correctly when the ‘www.’ is taken out ([http://izaca.com/blog](http://izaca.com/blog)).
   The PHP code that its referring to is below, but I don’t know how to fix it.
 *     ```
       if ( !function_exists('wp_redirect') ) :
       function wp_redirect($location, $status = 302) {
       	global $is_IIS;
   
       	$location = apply_filters('wp_redirect', $location, $status);
   
       	if ( !$location ) // allows the wp_redirect filter to cancel a redirect
       		return false;
   
       	$location = wp_sanitize_redirect($location);
   
       	if ( $is_IIS ) {
       		header("Refresh: 0;url=$location");
       	} else {
       		if ( php_sapi_name() != 'cgi-fcgi' )
       			status_header($status); // This causes problems on IIS and some FastCGI setups
       		header("Location: $location");
       ```
