IPN Issues

The paypal keep sending paypal ipn page is incorrect, and keep trying to post and because the email receipt is at the same page keeps send several emails to customers and is annoying. Code of page below. I need help because I don't see where the error is.
<?php
//WA eCart Include
require_once("WA_eCart/mbtCart_PHP.php");
?>
<?php
$mbtCart->GetContent();
?>
<?php
// WA eCart Get Form PaypalIPN.xml
if (WA_isValidPayPal()) {
$mbtCart->ClearCart();
$displayIndex = 0;
$runOnce = "run";
while (isset($_POST["item_number".($displayIndex+1)])) {
$ATC_AddIfIn = 0;
$ATC_RedirectIfIn = "";
$ATC_ID = "".$_POST["item_number".($displayIndex+1)] ."";
$ATC_Name = "".$_POST["item_name".($displayIndex+1)] ."";
$ATC_Description = "";
$ATC_Weight = "0";
$ATC_Quantity = "".$_POST["quantity".($displayIndex+1)] ."";
$ATC_Price = "".$_POST["mc_gross_".($displayIndex+1)]/$_POST["quantity".($displayIndex+1)] ."";
$ATC_size = "".$_POST["os0". ($displayIndex+1)] ."";
$ATC_SizesIncrease = "". $_POST["os1".($displayIndex+1)] ."";
$ATC_Thumbnails = "";
$ATC_sku = "";

if (is_numeric($ATC_Quantity) && $ATC_Quantity != 0) {
$mbtCart->AddToCart($ATC_AddIfIn, $ATC_RedirectIfIn, $ATC_ID, $ATC_Name, $ATC_Description, $ATC_Weight, $ATC_Quantity, $ATC_Price, $ATC_size, $ATC_SizesIncrease, $ATC_Thumbnails, $ATC_sku);
}
$runOnce = null;
$displayIndex++;
}
}
?>
<?php require_once("WA_Universal_Email/mail_PHP.php"); ?>
<?php require_once("WA_Universal_Email/MailFormatting_PHP.php"); ?>
<?php
if ((WA_isValidPayPal())) {
//WA Universal Email object="mail"
//Send Loop Once Per Entry
$RecipientEmail = "".((isset($_POST["payer_email"]))?$_POST["payer_email"]:"") ."";include("WA_Universal_Email/WAUE_ipnresponse_1.php");
$RecipientEmail = "mike@miraclebit.com";include("WA_Universal_Email/WAUE_ipnresponse_1.php");
$RecipientEmail = "ccdantas@ccdantaswebdesign.com";include("WA_Universal_Email/WAUE_ipnresponse_1.php");

//Send Mail All Entries
if (""!="") {
header("Location: ");
}
}
?>
<?php
// WA eCart Redirect
if ($mbtCart->redirStr != "") {
header("Location: ".$mbtCart->redirStr);
}
?>

But the email sends?

Sending the email is the last thing on the page, so it is strange that there is an error if the email sends.

I'd need to debug this. Can you send me FTP access?

Hi Ray FTP attached as well as the emails the user and site owner is receiving.

If you log into paypal and look at your ipn history, does it give any information on the error message? It just doesn't look like this page has an error.

Is there information from paypal that might help diagnose this?

I will ask the site owner to check. I have sent to site owner an email requesting him to provide the message of the failed IPN. I guess the repeating emails submission is because IPN failed and the IPN re-send them until get a success. Is what I am thinking what is happening.

It sounds like it, but it doesn't make sense since the email is the last thing on the page and it sends... so how can there be an error if the email sends?

The site owner told me he received emails from paypal informing the IPN page is failing. And I quote: PAYPAL SENT ME A NOTICE YESTERDAY SAYING “IPNS SENT TO www.miraclebit.com/ipnresponse.php ARE FAILING.

Do you have access to their paypal account? You can go in to the history and see which are failing, if they are still failing, and maybe get the error message.

It looks like your IPN is set up to use http:// but your site does an automatic https:// redirect. That could be the cause.

If you copy everything in that IPN Message textarea and send it to me, that would help me debug if you still have issues.

I sent instructions to site owner.
Thanks
