to trouble shoot, find this line:
$WA_redirectURL = "Mem_Detail.php?id=".((isset($_POST["WADAUpdateRecordID"]))?$_POST["WADAUpdateRecordID"]:"") ."";
and change it to :
//$WA_redirectURL = "Mem_Detail.php?id=".((isset($_POST["WADAUpdateRecordID"]))?$_POST["WADAUpdateRecordID"]:"") ."";
$WA_redirectURL = "";
then add this code at line 1:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
and this code after the body tag:
<?php if($_SERVER["REQUEST_METHOD"] == "POST") echo WA_DFP_AllUploadsDebug(); ?>
and post back the results after trying to test the uplaod.
