Direct Access to this location is not allowed.


前台永遠顯示這個錯誤，我打開這個樣板的index.php
發現內容在一開始有這幾句：
<?php
defined( '_VALID_MOS' ) or die( 'Direct Access to this location is not allowed.' );
// needed to seperate the ISO number from the language file constant _ISO
$iso = split( '=', _ISO );
// xml prolog - quirks mode
//echo '<?xml version="1.0" encoding="'. $iso[1] .'"?' .'>';
?>

請問這應該怎麼調整？
