to troubleshoot, edit this line:
$WA_redirectURL = "images_Detail.php?imageID=".((isset($_POST["WADAUpdateRecordID"]))?$_POST["WADAUpdateRecordID"]:"") ."";
to:
$WA_redirectURL = " ";
so that no redirect occurs
add this code at line 1:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
to turn error reporting on
and add this code after the <body> tag to show the upload results:
<?php echo WA_DFP_AllUploadsDebug(); ?>
post back the info these changes write to the screen after testing the upload.
