CiviCRM Community Forums (archive)

Using Wordpress 3.4.1 with CiviCRM 4.1.2 and Paypal Payments Pro with the recurring donations module/feature, my IPN notifications for the completion of recurring payments are not getting through, so said contributions stay pending indefinitely. Normal donations behave properly.

I initially had Paypal sending my IPN notifications to:

mydomain.org/wp-content/plugins/civicrm/civicrm/extern/ipn.php

but that produced failures with HTTP response code 500. Based on advice seen elsewhere on this forum, I then changed it to mydomain.org/ - which led to success as far as Paypal is concerned, but did not actually lead to CiviCRM receiving and responding to the notifications.

I thought the problem might be permissions, so I went into FTP and set the permissions on the ipn.php file to 755 as opposed to 744, which it was by default, and am now retrying an earlier IPN, but if anyone else has other thoughts about what might be going on or how to fix it, that would be much appreciated.

I took a look at the CiviCRM error logs for Cat Paquin's site and I searched on "ipn" and found no results.

Then we discovered that PayPal is looking for sites/all/modules/civicrm/extern/ipn.php i.e. a remnant of when CiviCRM was running in Drupal for this site. I adjusted this URL in the civicrm_settings table and I hope that will fix it.

Thanks, great hint. Got PayPal IPNs working in Drupal too: The CiviCRM Resource URL had been wrongly set at installation time (installed Drupal in a subdirectory instead of root). Setting it to http mydomain.org/sites/all/modules/civicrm solved the problem. (Also fixed CIVICRM_UF_BASEURL in civicrm.settings.php.)
