XF 1.2 nginx testcookie


Active member
I recently implemented the testcookie module on one of my XenForo sites, but noticed that the challenge page was causing issues with User Upgrades. The forum was failing to process the payment as being approved.

Can anyone share the flow of purchasing a user upgrade, so that I might know what pages to whitelist from the testcookie challenge? Or even better yet, what page Paypal tries to query to say the payment succeeded?
