Hi @andreaseriksson
Thank you for using Paid Memberships Pro, I’m really sorry to hear about this issue you are facing.
Would you mind sending through a list of your active plugins so I may have a look into this?
Do you have any custom code that may alter Paid Memberships Pro or a theme that integrates with Paid Memberships Pro?
Would it be possible for you to run a test checkout with only Paid Memberships Pro active and temporarily using TwentyNineteen theme to see if the issue persists at a very basic level.
Updated!
I switch over to an Stripe account that I have, and boom then it worked as it should, it returns the information that is needed for PMP. So I guess its something with my PayPal account, maybe.
I haven’t altered anything and did try to deactivate all plugin´s and just run with the standard theme, but that did not help.
I think the issue may be involved with the redirects back and forth between PayPal checkout. Does your site load only over https:// or can you access http:// or https://?
If you can access your site over either http or https, please look at forcing a redirect to only let connections of your site be served over https.
