Paypal not returning data

Posted in

I was hoping this would work out-of-the-box, but am having lots of problems with the data returned by PayPal. I’m not an expert in the technical end of things, so am trying to understand what is happening.
I’m currently using sandbox and the process works as it should (I can subscribe, get redirected to PP then back to the Thank You page). However, my thank you page is blank. I.e, [groups_paypal_return] is empty. Also, the user that makes the payment should be automatically subscribed to that subscription group, but that too does not happen.
My test page is here:


Things I’ve tried/checked the following:
– Made sure IPN url is correctly set in my sandbox account.
– Made sure I’m not getting an security certificate error. I’m using https and when I check the notification URL that you specify, I don’t see errors (I get a blank page).
– I added the suggested debugging lines in wp-config.php . Unfortunately there is no error log created in wp-content subdirectory or anywhere else. I even defined the path in WP_DEBUG_LOG, but no log file is ever written. At one point I even set WP_DEBUG_DISPLAY to true and saw one error displayed on the page, but it was unrelated and I fixed it. But I get no other errors.
Your help is most appreciated/needed.

    Hi Mike, welcome back to our support forum.

    We can definitely help you with your issue and for the tests it would be most useful to keep WP Debugging on and send us temp admin credentials for your site to george at itthinx dot com, mentioning the topic title in the mail subject. I think it’s better to check the setup and try buying a subscription using my own sandbox credentials to find out what might wrong there.

    Kind regards,
