pengembangan plugin – Kelas aktivator saya tidak menjalankan kode di dalamnya

Saya menggunakan Boilerplate Plugin WP dan saya membutuhkan file dan pemberitahuan admin dalam kelas aktivator tetapi panel Kirki saya tidak muncul di penyesuai dan pemberitahuan admin tidak muncul. Saya juga tidak mendapatkan pesan kesalahan apa pun.

Juga PLUGINPATH diatur ke plugin_dir_path( __FILE__ ).

class Wp_Portfolio_Pro_Activator {

    /**
     * Short Description. (use period)
     *
     * Long Description.
     *
     * @since    1.0.0
     */
    public static function activate() {
        // Require Kirki and setting for plugin build on framework.
        self::load_files();

        add_action( 'admin_notices', array( __CLASS__, 'admin_notice' ) );
    }

    public static function admin_notice() {
        $message="<div class="notice notice-success"><p>";
        $message .= sprintf( __( 'Hello %s!', 'my-plugin' ), '<strong>' . get_current_user_name() . '</strong>' );
        $message .= '</p><p>';
        $message .= __( 'Thank you for downloading WP Portfolio Pro. Edit the setting from the customizer.', 'wp-portfolio-pro' );
        $message .= '</p>';
        $message .= '<a href="' . esc_url( admin_url( 'customize.php?customize_changeset_uuid=' . get_theme_mods_changeset_post_id() ) ) . '"><button>Go to settings</button></a></div>';
        echo $message;
        printf( '<div class="notice notice-success is-dismissible">%1$s</div>', $message );
    }

    public static function load_files() {
        // Require Kirki and setting for plugin build on framework.
        require_once PLUGINPATH . 'includes/kirki/kirki.php';
        require_once PLUGINPATH . 'includes/wp-portfolio-pro-kirki.php';
    }

}

Ini adalah kode di file utama yang terhubung ke hook aktivasi.

/**
 * The code that runs during plugin activation.
 * This action is documented in includes/class-wp-portfolio-pro-activator.php
 */
function activate_wp_portfolio_pro() {
    require_once plugin_dir_path( __FILE__ ) . 'includes/class-wp-portfolio-pro-activator.php';
    Wp_Portfolio_Pro_Activator::activate();
}

/**
 * The code that runs during plugin deactivation.
 * This action is documented in includes/class-wp-portfolio-pro-deactivator.php
 */
function deactivate_wp_portfolio_pro() {
    require_once PLUGINPATH . 'includes/class-wp-portfolio-pro-deactivator.php';
    Wp_Portfolio_Pro_Deactivator::deactivate();
}

register_activation_hook( __FILE__, 'activate_wp_portfolio_pro' );
register_deactivation_hook( __FILE__, 'deactivate_wp_portfolio_pro' );
