Error "undefined variable" saat laravel di hostingkan

mohon maaf sebelumnya saya pertama kali menghostingkan laravel ,nah pada saat upload saya mengeluarkan file index public agar terbaca oleh cpanel, masalahnya kok variable di view saya tidak bisa terbaca,saya juga sudah install laravel lewat "softacoulus" dari cpanel bisa setelah itu saya ganti folder "app", "route" dan "resource" namun tetap error undifinied,apakah controller saya salah atau proses upload saya yang salah,soalnya saya coba di "localhost" bisa jalan. ? ini source code dari controller saya

function show(){
        $data_produks= data_produk::take(6)->get();
        $latest_posts=data_produk::take(3)->OrderByDesc('tanggal')->get();
        $data_iklans=data_produk::take(2)->OrderByDesc('tanggal')->get();
        $data_slideshows= slideshow::all();



        return view('home',compact('data_produks', 'data_slideshows','latest_posts','data_iklans'));
    }

dan ini source code route saya

 Route::get('/', function () {
    return view('home');
});
Route::get('home','Home_Controller@show');
Route::get('produk','ProdukController@show');
Route::get('about','AboutController@show');
Route::get('contact','ContactController@show');

dan ini source code view homenya

$response = $kernel->handle(

$response->send();

$kernel->terminate($request, $response);

dan ini errornya seperti ini :
