Joomla 3.5.1 CiviCRM 4.7.7 Contribution Page setup with Paypal as payment processor. Page completes, Payment completes in Paypal. Paypal sends confirmation Email. Paypal shows IPN record. Shows status of 200 (OK?) Contribution payment is not updated to completed, membership remains in pending (as expected) and no email from CiviCRM goes out to member. If I add and use the paylater option the email from CiviCRM goes out to the member. First noticed this in March April time frame with an event.

In joomla looking at most recent log in ConfigAndLog under Media/civicrm

If PayPal is saying the IPN went through correctly, it's worth checking to see what the URL PayPal is using for the IPN. Does it match what you're expecting? Can you find your Apache (or nginx) web server logs and correlate them with PayPal? Are they also showing a 200? Or perhaps a redirect of some sort?

  • isfpta.org/components/com_civicrm/civicrm/extern/ipn.php (and more details). We moved to https: several years ago. Checking Apache logs. May 16, 2016 at 12:22
  • I have looked through our web usage and web error logs viewable through PHPAdmin. The error log has a considerable number of PHP Notice(s). One that shows up repeatedly is: Array to string conversion in /home/isfptaadm/domains/isfpta.org/public_html/administrator/components/com_civicrm/civicrm/CRM/Contribute/Form/ContributionBase.php on line 650. I don't think it relates to the IPN transaction as the referring site is our schools. I am inclined to think this happens as our schools site calls our site's civicrm contribution page.

  • @DonaldKnapp Besides the errors - can you confirm that you're seeing 200 (success) HTTP codes for requests to the IPN page? May 18, 2016 at 21:35
  • here is one. - - [19/May/2016:07:31:36 +0800] "POST /components/com_civicrm/civicrm/extern/ipn.php?reset=1&contactID=5685&contributionID=8429&module=contribute&membershipID=3941 HTTP/1.1" 200 44877 "-" "PayPal IPN ( paypal.com/ipn )" May 19, 2016 at 4:54
