严格标准：不应在第13行的ad / index.php中静态调用非静态方法MAD_Admin_Redirect :: redirect（）

Question

I have used madserve and I have installed it but I get this error:

Strict Standards: Non-static method MAD_Admin_Redirect::redirect() should not be called statically in /home3/******/public_html/ad/index.php on line 13

What I can do?

index.php

<?php
    define('ROOT_INDEX', true);
    // Require the initialisation file
    require_once 'init.php';

    // Required files
    require_once MAD_PATH . '/functions/adminredirect.php';

    // Redirect to the admin interface
    if (MAD_INSTALLATION_STATUS == MAD_INSTALLATION_STATUS_INSTALLED)
    {
        MAD_Admin_Redirect::redirect();
    }

?>

/functions/adminredirect.php

<?php
    class MAD_Admin_Redirect
    {

        function redirect($adminPage = 'www/cp/index.php')
        {
            header ("Location: ".$adminPage."");
        }
    }
?>

You need to mark MAD_Admin_Redirect::redirect as static

<?php
class MAD_Admin_Redirect
{

    public static function redirect($adminPage = 'www/cp/index.php')
    {
        header ("Location: ".$adminPage."");
    }
}
