No login error

the problem is this function

add_action('wp_login_failed', 'wma_login_fail');

function wma_login_fail($username){
    // Get the reffering page, where did the post submission come from?

    if (isset($_SERVER['HTTP_REFERER'])) {

        $referer = parse_url($_SERVER['HTTP_REFERER']);
    	$referer= '//'.$referer['host'].''.$referer['path'];

        // if there's a valid referrer, and it's not the default log-in screen
        if(!empty($referer) && !strstr($referer,'wp-login') && !strstr($referer,'wp-admin')){
            // let's append some information (login=failed) to the URL for the theme to use
            wp_redirect($referer . '?login=failed');
        exit;
        }
    }
}

That overwrite the error show into the default account page of woocommerce
