这个错误是众所周知的，无论我在哪里看到它，要么我没有做：

<form method="post" action="options.php">

或者我没有注册我的选项，这与以下类中的情况不同：

class CoreTheme_AdminPanel_Admin implements AisisCore_Interfaces_Admin{

    public function __construct(){
        add_action(\'admin_menu\', array($this, \'menu_setup\'));
        add_action(\'admin_init\', array($this, \'register_settings\'));

        add_option(\'success_message\', false);
    }

    public function init(){}

    public function menu_setup(){
        add_menu_page(
            __(\'Aisis\', \'aisis\'), 
            __(\'Aisis\', \'aisis\'), 
            \'edit_themes\', 
            \'aisis-core-options\', 
            array(
                $this, 
                \'build_template\'),  
                get_template_directory_uri() . \'/images/block.png\', 
                31
            );

        add_submenu_page(
            \'aisis-core-options\', 
            __(\'Aisis BBPress Options\', \'aisis\'), 
            __(\'Aisis BBpress Options\', \'aisis\'), 
            \'edit_themes\', 
            \'aisis-core-bbpress\', 
            array(
                $this, 
                \'build_template\'
            )
        );

        add_submenu_page(
            \'aisis-core-options\', 
            __(\'Aisis Packages\', \'aisis\'), 
            __(\'Aisis Packages\', \'aisis\'), 
            \'edit_themes\', 
            \'aisis-core-packages\', 
            array(
                $this, 
                \'build_template\'
            )
        );

        add_submenu_page(
            \'aisis-core-options\', 
            __(\'Aisis Update\', \'aisis\'), 
            __(\'Aisis Update\', \'aisis\'), 
            \'edit_themes\', 
            \'aisis-core-update\', 
            array(
                $this, 
                \'build_template\'
            )
        );
    }

    public function register_settings(){
        register_setting(
            \'aisis_options\', 
            \'aisis_sitedesign\', 
            array(
                $this, 
                \'option_validator\'
            )
        );
    }

    public function build_template(){
        $template = AisisCore_Factory_Pattern::create(\'CoreTheme_Templates_Builder\');
        $template->render_template(CORETHEME_ADMIN_TEMPLATES . \'coretheme.phtml\');
    }

    public function option_validator($input){
        $option = get_option(\'aisis_core\');
        $option = $input;
        update_option(\'success_message\', true);
        return $option;
    }
}

那我为什么会犯这个错误呢？，我的设置已注册，表单已呈现，一切似乎都很好。。。。
