CiviCRM Community Forums (archive)

Hi, we recently changed our domain name, and did a thorough flushing of caches etc. However, the URL used by Paypal Standard IPNs doesn't seem to have changed to reflect the new domain name. Paypal sent us a message saying IPNs sent to these URLs are failing:

http://our-old-domain.com/sites/all/modules/civicrm/extern/ipn.php?reset=1&contactID=971&contributionID=106&module=contribute&membershipID=1253&contributionRecurID=6&contributionPageID=3

http://our-old-domain.com/sites/all/modules/civicrm/extern/ipn.php?reset=1&contactID=725&contributionID=428&module=contribute&membershipID=1384&contributionRecurID=37&contributionPageID=16

We can see that recurring payments ceased being tracked after changing the domain.

Also, after changing our domain, a couple of days later we added SSL. Will that have any ramifications?

Where can we go to set all our recurring payments so they are using the correct IPN URLs?

Thanks for your help.

(By the way this is what we did to clear caches after changing our domain:)

Empty the Drupal performance cache
Empty the Drupal Views cache - see Views / settings / advanced
Rebuild permissions cache - Reports > Status Report > scroll to Node Access permissions and Rebuild permissions.
Run the CiviCRM scheduled job (Admin>System settings>Scheduled jobs) - clean up temporary data and files
Then access PHP MyAdmin - empty/truncate all tables with the word ‘cache’ in their title (drupal and civi). We need to do that in the separate Civicrm and Drupal databases, because, even thought the civi tables are still in the Drupal database, they’re not being used!
Then truncate the session table. (You select the table and in the bottom of the screen action menu select Empty)
Then via FTP:  empty the following directories (this is much quicker in cPanel file manager than in Filezilla):
<drupal-root>/sites/default/files/civicrm/templates_c/*
<drupal-root>/sites/default/files/civicrm/ConfigAndLog/Config.IDS.ini
<drupal-root>/sites/default/files/civicrm/ConfigAndLog/*
<civicrm_custom_extension_folder>/cache/*

Sorry, it's taken a while to reply to this with our findings:

We use: Paypal website standard, on a business account, and it does the following:

It has a field where you can change your IPN URL, so naturally its very important to make that change if you are changing your domain name. Paypal > My Account > Profile > Selling preferences, Instand Payment Notification preferences.

However, whenever a user sets up a payment profile (ie a recurring payment), the IPN URL is recorded for that profile. So if you change your domain name, then all the users' profiles set up before that date will have the old domain's IPN URL recorded with them.
It's therefore necessary to ensure you have a rewrite rule (eg in .htaccess) to ensure that the old IPN URLs will be forwarded to your new domain.

Paypal doesn't like it when IPN URLs fail on your account. They make it a policy to remove all IPN URL notifications if you have persistant failures, so you'd lose all IPN functionality if you don't attend to the above points. Not a very helpful scenario!

Finally, you can only have one IPN URL set within your account's settings. While individual profiles may have earlier IPNs attached to them, you can only have one current one.

Hope that all makes sense!
