php網站顯示空白的有關問題

php網站顯示空白的問題！
錯誤提示等都開了！
windows 2003 系統，php5.3 , mysql 5.5

這是 php探針 http://a858158288.us006.dbidc.pw/tz.php


這是 出錯網站： http://a858158288.us006.dbidc.pw/



這是 index.php 的代碼：

$file = "./include/lock.txt";
if(!file_exists($file))
{
header("Location: ./install");
}

require('include/conn.php');
$siteconfig="select * from phpsou_siteconfig";
$site_query=mysql_query($siteconfig);
while($site=mysql_fetch_array($site_query,MYSQL_ASSOC)) 
{
$title=$site['adtitle'];
$name=$site['name'];  
$keywords=$site['Keywords'];
$description=$site['description'];
}
$smarty->assign("title",$title); 
$smarty->assign("name",$name); 
$smarty->assign("keywords",$keywords); 
$smarty->assign("description",$description); 



$sql="select * from phpsou_about where is_show order by sortid asc";
$cate_query=mysql_query($sql);
while($cate=mysql_fetch_array($cate_query,MYSQL_ASSOC)) 
{ 
   $about[]=array("title"=>$cate[title],"about_id"=>$cate[about_id],"url"=>$cate[url]); 
} 
$smarty->assign("about",$about); 

$smarty->display('index.tpl');
?>

------解決思路----------------------
是不是缺少了index.tpl
------解決思路----------------------
什麼錯誤，Bad Request (Invalid Hostname)
------解決思路----------------------
Bad Request (Invalid Hostname)
錯誤的請求（無效的主機名稱）

http://us006.dbidc.pw 是有效
如果這就是你的，那麼是泛網域名稱解析有誤
