Paypal invalid transaction + no confirmation

-- HikaShop version -- : 2.3.2
-- Joomla version -- : 2.5.18
-- PHP version -- : 5.3.28

Hi,

Since a few weeks for every Paypal payments that is made on my clients website I receive the following error message by email:

Paypal payment notification refused:invalid transaction
A paypal notification was refused because it could not be verified by the paypal server

Check the documentation concerning this issue at www.hikashop.com/index.php?option=com_up...pal-error#invalidtnx
This notification was for the order ######## on the website XXXXXXXXXXXXXX
You can access the order details directly by clicking on the link below after logging in your back end:

The Paypal payment does get through and money is received, but the orders are no longer set to the confirmed status automatically anymore.

I have attached a screenshot of the settings in the Hikashop Paypal plugin.

Could you please advice me in how to fix this?

Kind regards,
Chris

Hi,

Have you read the indicated documentation ?
www.hikashop.com/index.php?option=com_up...pal-error#invalidtnx

Do you have any errors returned in the payment log file in Configuration > Main > Files ?

Hi Xavier,

Thank you for your quick reply.
The documentation for this error does not give much helpful information. It just stated that notifications are checked to see if they originated from a known Paypal server, and that if they are not the message can be ignored. The problem is that the message should come from a Paypal server since they are the direct result of a paypal payment.

Clicking "See the Report" under Configuration > Main > Files gives me the message "The log file is empty".

Kind regards,
Chris

Hi Nicolas,

I have enabled the debug option for the Paypal plugin and collected a few transactions in the log. Most of what is in the log file is not very clear to me, but all separate transactions that are logged and with the following lines:

INVALID

invalid transaction

Can i send you the log so that you can tale a look at it to see what is going wrong?

Kind regards,
Chris

Hi Nicolas,

Thank you for your help. I have made the change to paypal.php as you suggested, but the same issues as I described before are still present. An order paid for through Paypal is still not confirmed, the email with the warning message is still sent to the administrator and the error log looks the same.

Kind regards,
Chris

Hi Again,

Have you got any idea what else could be causing this, and what I can do to fix it?
Paypal not functioning properly is quite annoying for this website since it is a frequently used payment method.

Kind regards,
Chris

Hi Nicolas,

Sorry for my own slow reply.
I have had a look at the IPN history in the Paypal account linked to the webshop. I don't know what to look for however. As far as I can see everything looks normal. I will send you a screenshot of the pages and the IPN message, as well as the corresponding Hikashop error log through email.

Kind regards,
Chris

Hi Nicolas,

I have tried your suggestion, but I do not see any effect. The order still stays at the 'created' status and is not 'confirmed'.
Do you want me to email you the error log and IPN log again?

Kind regards,
Chris

Hi Nicolas,

I have been busy with other project so this issue got put on hold for a bit. I would still very much like to fix this though.
I have emailed you the Paypal Log file and the Paypal IPN messages for the three most recent Paypal transcations. All of these still give the following error message email:


Hello,
A paypal notification was refused because it could not be verified by the paypal server

Check the documentation concerning this issue at www.hikashop.com/index.php?option=com_up...pal-error#invalidtnx
This notification was for the order ORDERNUMBER on the website WEBADDRESS
You can access the order details directly by clicking on the link below after logging in your back end:

Hi Nicolas,

Thank you for your solution. I don't think this is ideal, but at least the orders are automatically confirmed again now.
I have used the IP addresses for ipnpb.paypal.com that are listed at this page: ppmts.custhelp.com/app/answers/detail/a_id/92 and it appears to work.

Kind regards,
Chris

Hi, I am having this exact same problem, I have I tried the last fix that Foxworks says is ' I don't think this is ideal' and it seems to work.

Is it good to use this fix? have there been any other forum fixes other that this one?
