Error Entering Code

Hi,

When I try to add this code:

// Custom Login Branding
// Adding the function to the login page
add_action('login_head', 'custom_login');

// Our custom function that includes the custom stylesheet
function custom_login() {
	echo '<link rel="stylesheet" type="text/css" href="' . get_bloginfo( 'stylesheet_directory' ) . '/login.css" />';
}

function my_login_logo_url() {
	return get_bloginfo( 'url' );
}
add_filter( 'login_headerurl', 'my_login_logo_url' );

function my_login_logo_url_title() {
	return get_bloginfo( 'title' );
}
add_filter( 'login_headertitle', 'my_login_logo_url_title' );

I get a 403 error. In particular if I leave out this line:

echo '<link rel="stylesheet" type="text/css" href="' . get_bloginfo( 'stylesheet_directory' ) . '/login.css" />'; it saves fine but I put that line back in and I get the 403 error code again.
