hello, Drbyte,

Really sorry for my recklessness.

I re-set as per your suggestion, but ended up as a blank page.
after i set error reporting to TURE,
HTML Code:
$startingDir = getcwd();
  $zcDir = realpath(dirname(__FILE__));
  chdir($zcDir);
	define('STRICT_ERROR_REPORTING', ture);
so that can see errors. so many error displayed as follows.

Many appreciated for your furhter suggestion.
