Saya sudah jelaskan penyebabnya di http://www.myphptutorials.com/questions/beda-di-localhost-dan-saat-di-onlinekan_204.html#answer-anc1240
Disini tempat kesalahannya:
<p class="align-right">- Agus Sumarna</p>
 </div>
 
	<?php 
 if(isset($_GET['page'])){
 	$page=htmlentities($_GET['page']);
 }else{
 		$page="form_daftar";
 }
 
 $file="$page.php";
 $cek=strlen($page);
 
 if($cek>30 || !file_exists($file) || empty($page)){
 	include ("form_daftar.php");
 }else{
 	include ($file);
 }
 ?>
