Well, i don't see the error reporting code on the last page you sent.
If the updates are working, i cont see why the redirect would not occur if there is not an error on the page.
the redirect page is set at line 221:
$WA_redirectURL = "untitled.php";
then gets executed at line 251:
header("Location: ".$WA_redirectURL);
what happens if you change line 251 to:
die("Redir: ".$WA_redirectURL);
header("Location: ".$WA_redirectURL);
