PayPal Payments Standard just stopped working

**clint6998** · 11 Feb 2013, 05:26 PM

PayPal Standard has been set up and running fine for months and then starting late last week I noticed that I stopped getting notifications from my cart about orders, but was still getting emails from PayPal that I had money received. I checked to make sure that the token, IPN and return URL were set right and they are. When someone checks out using PayPal, not only do I not get a notification of a new order from my store, but when it redirects back to my site, on the checkout_success page it shows the order number of the last correctly processed order.

Has anyone had this problem before or knows what I need to do to fix this? I get on average about 200 orders per month and this is killing me.

Thank you for anyone who can help!

turn on paypal logging and let us see what is happening, make sure you ommit any personal information from the paypal IPN notification to ensure you protect your customers details for the forum.

have you recently set a sale up? I have had rounding issues recently where zen cart rounds up to 4 decimals but paypal only to two, and when a slae is active and you are talking items in cart with fration prices there is a mismatch when the orders are sent back from paypal.

if you have line items on your paypal store receiptss you will easily be able to see if this is the problem, simply add all the items as per the order to your cart, if the total is 1p or 1c different to the paypal receipt, then this is definatly why the orders are not processing.

I set it to log and downloaded the HTML file and it comes up blank. looked at source code and also blank. I added one product as a test for 1.00 and and also purchased 2 other items from my store (one that was existing and one that was added this weekend). two purchases showed up in the admin section and one didnt (the test purchase). Only one email received from my cart of a new order which was the last one.

Ok, I was looking in the wrong spot. Here is an IPN error I am seeing:

IPN ERROR :: Could not find stored session {004ct9vg4iv7gi9rl98jril5a5} in DB; thus cannot validate or re-create session as a transaction awaiting PayPal Website Payments Standard confirmation initiated by this store. Might be an Express Checkout or eBay transaction or some other action that triggers PayPal IPN notifications.

Feb 11 2013 10:19 -- IPN ERROR :: No pending Website Payments Standard session data available. Might be a duplicate transaction already entered via PDT.

Feb 11 2013 10:19 -- NOTICE: IPN Processing Aborted due to missing matching transaction data, as per earlier debug message. Perhaps this transaction was already entered via PDT? Thus there is no need to process this incoming IPN notification.

Here is the full log:

So your paypal log file is empty?
includes/modules/payment/paypal/logs
Should be around about there?

What I would check is if orders of products that are a round figure and don't have a sale applied to them get processe vs an order of products in a sale.?

ok, so I found the file (was looking in the wrong cart) but every time I try posting it it will not let me. My post does not show up. All numbers are rounding to 2 digits.

**DrByte** · 11 Feb 2013, 06:44 PM

Is there a very specific reason why you're still using the antiquated Payments Standard approach instead of the contemporary Express Checkout? They provide the same experience to the customer but EC works much more reliably and never has to wait on an IPN to process the order.

**clint6998** · 11 Feb 2013, 06:46 PM

Here are the errors from the log though:

IPN NOTICE :: IPN pausing: waiting for PDT to process. Sleeping 10 seconds ...

Feb 11 2013 10:19 -- IPN ERROR :: Could not find stored session {004ct9xxxxxxxxxxx8jril5a5} in DB; thus cannot validate or re-create session as a transaction awaiting PayPal Website Payments Standard confirmation initiated by this store. Might be an Express Checkout or eBay transaction or some other action that triggers PayPal IPN notifications.

Feb 11 2013 10:19 -- IPN ERROR :: No pending Website Payments Standard session data available. Might be a duplicate transaction already entered via PDT.

Feb 11 2013 10:19 -- NOTICE: IPN Processing Aborted due to missing matching transaction data, as per earlier debug message. Perhaps this transaction was already entered via PDT? Thus there is no need to process this incoming IPN notification.

See if any logs mention a currency mis match.

Also as I said do a test with products that do not have a sale applied.
