Paypal Standard not confirming transaction

[Barnacle]

Hi,

Ever since I upgraded to 4.5.2, payment transactions have failed to complete and been left in "Pending from incomplete transaction" status, which means that confirmation emails are not sent even when the payment has completed as far as Paypal is concerned.

The log shows this info line:

Code: [Select]

[info] returning since contribution status is pending
Is there something not getting triggered when Paypal Standard returns to the site?

I had some problems too with IPN from PayPal and it looks like it was related to PayPal shutting down SSLv3 due to the Poodle vulnerability. PayPal even sent me a PDF about this, suggesting to use TLS in the place of SSL.
In my specific case PayPal was repeating the IPN 16 times each, what lead Civi to send 16 confirmation emails do contributors. PayPal was not being able to see that Civi was acknowledging the payments, but I thing other error could happen.
Here, it looks like I was able to solve the problem shutting down the "Verify certificate" option in CiviCRM administration. But I'm waiting more transactions to see if it's OK now. Maybe you could try that there.

Thanks for the advice!

In my case it turned out that our client had changed the email address for login to Paypal without informing us. Therefore, we didn't change it in the CiviCRM config. The transaction still went through, but Paypal marked it as 'pending' rather than completed without telling us why.
