PayPal IPN issues with Auto Return

For a while, everything worked fine, but now orders are not showing up in my admin section....so here I am.

As for getting notified about a payment, you can set up Paypal to email you every time you get a payment. So that should take care of missing orders, however I still need to contact the customer (immediately) to confirm what they ordered. I also worry that when they log back in, there will be no record of their order.

I have contacted Paypal, but I am sure that will go nowhere.

I am using 1.3.7, will that mod listed in this thread work on my site. Does it fix the problem? I added text to tell customers to return to the site, but that is no guarantee.

Hi all...any news about the PayPal IPN issue? On my side I keep having no notifications on ZC after an order is completed and paid. I am using the sandbox and once in a while the whole procedure works in the correct way but it's not constant, at least from my side. Any other information is appreciated. I just ask myself how it's possible that PayPal has the IPN service not working for so long and if that affects also other kinds of shopping cart systems (it should, if the problem is on the PayPal site...) but I cannot believe that millions of websites already using PayPal as a payment gateway go through this kind of problems as we do...

What is actually strange, i have no cart left
in the recover cart modules, which makes me think that the cart has somehow been by accessing "checkout_success". A wrong IPN could be a clue, having a query to fail.
I am having this problem too. The order is not being created at all, and the inventory is not being subtracted, yet the cart empties.

I set up another Zen Cart on the same server with no trouble, so I don't think it has anything to do with server settings.

Check/Money Order works just fine.

The payment notifications I get from paypal have in the subject line: Item #Store Receipt.

Inside the e-mail:

Item/Product Number: Store Receipt
Item/Product Name: Homicide Rocker Purchase

I'm also getting an error in the catalog side log that reads:

PHP Warning: Division by zero in /home/homicide/public_html/includes/modules/order_total/ot_coupon.php on line 364
[08-Jul-2008 17:37:13] PHP Warning: Division by zero in /home/homicide/public_html/includes/modules/order_total/ot_coupon.php on line 364

At the time of that log, the ot_coupon module was not enabled.

I can't figure this out; anyone have any ideas?

Do you have logging turned on for both paypalwpp and paypaldp? Would you mind posting the logs of the transaction (after removing customer info)?

Were any of the items purchased on sale or special?

Thanks, Dr. Byte, for linking me to that thread. That's exactly what I was looking for, and it did solve most of the problems.

However, when customers use a discount code in their order, I still have the trouble of not getting the order. I get this error message:

PHP Warning: implode() [<a href='function.implode'>function.implode</a>]: Invalid arguments passed in mysite/includes/modules/payment/paypal/paypal_functions.php on line 506

Line 506 is: $info = implode("", $info);

And this log is from the PayPal debugger:

IPN FATAL ERROR :: Could not establish fsockopen.
Host Details = http://proxy.shr.secureserver.net:3128 (0) Unable to find the socket transport "http" - did you forget to enable it when you configured PHP?

Without using a discount code, everything is fine.

Thanks again for everyone's help.:hug:

Although i made paypal accounts not an option,
to force auto-redirecting customers back to the shop,
because no account signup is shown to the customer,
he has already got one.

paypal payments don't send IPN to the zencart,
only getting an email and no trace of the order.
:lamo:

A) is push order a valuable option ?
B) how can i retrieve those carts ?
C) what about creating a pending order before sending the customer to
paypal, as proposed earlier in this thread ?

A) PAYPAL session viewer is working fine. pushorder helps you quickly create the order w/o embarrassement having to contact the customer to know what he ordered. B) + C) is also somehow solved. One tip, clean you paypal sessions table to make it easier and faster to use.

Came across this thread, talking about paypal PDT + token,
so i activated this too.

I had this same issue and this thread helped:
http://www.zen-cart.com/forum/showthread.php?t=107406&highlight=2013+Lost+connection+MySQL+server+query

I use godaddy and after setting cURL proxy status to false, my issue was resolved.

That did it Dr Byte! Thanks! Hopefully GoDaddy will send out a notification next time a simple change like that happens. I lost a couple business days because of it! Thanks again!

i still have the problem of the IPN not working,
maybe someone can hint me where to check if you consider that the bug only affects "localized" browsing customers.
it's not firewall related.
