Unable to verify paypal sandbox error

I am trying to make paypal IPN work and is testing with paypal sandbox… All I get is this error message in the log but no users are created. The custom variable reads “www.forummarketing.com” which is the right domain.

I feel a little bit ignored here. Should I provide any kind of additional information?

Hi Andre.

Could you try the tests suggested in this article? Knowledge Base » Common Troubleshooting Tips

Also, it’s best to test with live transactions, even if 1 cent, rather than the Sandbox. The Sandbox sometimes introduces its own problems which wouldn’t even be in the real transactions.

I have tried with live transactions and the same error occur. Or I should probably clearify:

It works with the buttons generated by s2member.com. But I also want the regular IPN from paypal to work. So if I receive payments in any other way it creates the correct membership at my site.

Thanks for the follow-up.

I’m not seeing anything that’s jumping out at me in your logs. We’d need to run test transactions on your installation of s2Member and see your unedited logs to be able to find the problem here.

Could you please give us a Dashboard login via Private Contact Form?

See: s2Member® » Private Contact Form

I opened up a support ticket for this over a week ago and hasn’t received an answer yet. Did I miss something? Should I start a new ticket?

Thank-you for the details.

We’re sorry for the delay, we usually wait for a notification from the User (you), and get back to you that way, as we get a large amount of private contact form submissions. If you submit the private contact form in the future, please update us on that fact if we don’t get right back to you so we can know you submitted it. :-)

I’m taking a look at your installation now.

When you use buttons not created with the s2Member shortcode for them, you need to add some values that s2Member needs. This article should help you with that: Knowledge Base » Using Buttons Generated @ PayPal.com
