Paypal Payment Notification problems since upgrade

Since I upgraded from Hikashop Essential 2.2.0 to Business 2.2.3 I've had some serious Paypal problems. I upgraded on December 12th, and since then I've had 4 out of 18 orders with problems where they will not automatically confirm after Paypal payments. This has never happened before in thousands of orders using Hikashop.

Basically, customers checkout on my site, are redirected to Paypal, make the Paypal payment. I receive a notification from Paypal of a successfully completed Paypal payment - but I don't receive an email from Hikashop letting me know a new order was confirmed. When I check, the order is still marked as 'created'. In the order history, there is nothing except the creation date.

What is going on? Right now I have to manually confirm orders which is simply not an option long-term, I don't have the resources to do it.

Hi nicolas,

Thanks for the reply.

What I am saying is this NEVER happened before I upgraded, in over a year of Hikashop usage. Now it is happening randomly (as I said, 4 out of 18 orders since the upgrade)

I checked the documentation you provided, but everything there looks like it should be in order. I have not made any changes to my website in a few months, other than upgrading to HikaShop business.

Nothing in common, so far as I can tell! Except that they all happened in the last 3 days.

Ok, I just got another order and it also did not process properly. Apparently every order in the last 3 days has not processed properly. So it isn't random, it's just broken now and I can't say why.

I turned on 'debug' in the Paypal plugin and checked the log after the last order. I didn't get anything useful at all. This is the contents of the logfile:

"Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification Could not load any order for your notification "

Any ideas nicolas? I really need this working - about to leave on holidays and I can't manually confirm orders during that time! I could give you Superuser access if that's helpful.

Nicolas,

I just got an email from Paypal:
"Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

nucleus-soundlab.com/index.php?option=co...t&lang=en&Itemid=123

If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.

Thank you for your prompt attention to this issue."

What is going on? Please, I need some ideas here. Paypal will disable my IPNs if I don't do something.

Hi Nicolas,

Thanks for the reply. Unfortunately I'm still having the problem.

The only plugin I have added lately is the WebEngage poll plugin. I uninstalled that completely. Now I've had more orders come through, but still payment notification publishing is not working.

I even checked my FTP server 'plugin' and 'component' folders for anything that is more recent than the Hikashop upgrade (by looking at modified dates), and there are no modified folders newer.

Any other ideas? I also reinstalled Hikashop - no change.

Hi Nicolas,

I checked the logs. I'm not sure exactly what to look for other than the URL. Here is one of the logs from yesterday (IPN not working):
173.0.81.1 - - [23/Dec/2013:13:26:53 -0500] "POST /index.php?option=com_hikashop&ctrl=checkout&task=notify¬if_payment=paypal&tmpl=component&lang=en&Itemid=123 HTTP/1.1" 200 8651 "-" "PayPal IPN ( www.paypal.com/ipn )

And here is one from when it was working:
173.0.81.1 - - [30/Nov/2013:13:14:38 -0500] "POST /index.php?option=com_hikashop&ctrl=checkout&task=notify¬if_payment=paypal&tmpl=component&lang=en&Itemid=123 HTTP/1.1" 200 8192 "-" "PayPal IPN ( www.paypal.com/ipn )"

Would it be helpful if I attached the whole log?

Hi Nicolas,

I never turned off debug - it's been on since this problem started. I went back and checked the log again and it's identical as far as I can tell. Just the same "could not load any order for your notification" repeated...

Not only that but in my ftp software it shows this logfile as last modified 12/7/2013. That doesn't sound like anything has been logged in weeks, unless I'm misunderstanding?

Any other ideas Nicolas? As you say, the payment notification is received by my website, according to the logs. Where does that leave us?

I just discovered the Paypal IPN History page. Not sure if this info would prove helpful in troubleshooting my problem?

My IPN history says the transaction retries 16 times and then fails. Well, actually some retry a random number of times and then are considered 'sent' although the order never successfully confirms in Hikashop. But most are failed with 16 retries. I've taken a screengrab of both the failed IPN and an IPN with 14 retries and attached them.

Hi Nicolas,

I've been in contact with my hosting provider, Stablehost. I gave them pretty much the same info I gave you and eventually they determined that there was a server-wide problem effecting Paypal IPNs. I was switched to a new physical server and now the problem seems to be fixed!

It is extremely hard to fathom how this could be possible without other people complaining (apparently it was just me and one other with problems). Stablehost blames Paypal. For me, I will probably get hosting elsewhere once my contract with them expires - just to be safe.

Anyway Nicolas, thank you so much for the assistance. I would suggest that in your FAQ about IPN problems, you mention two things:
-Check IPN History in your Paypal dashboard.
-Talk to your server provider about the problem, and provide the IPN History

Happy New Year!
