While using OptimizePress membership plugin: When a new user submits a payment through paypal, they are redirected to create a new user on my wordpress site.
But after creating the user, a cookie/whatever does not pass the paypal information to the new user account, and thus the user is stuck as a ‘free member’ rather than a subscribed member.
This issue is only present when Varnish is enabled.
In the thread below, a few cookie exceptions were added to Varnish:
Anyone figure out which cookie exceptions/page exceptions must be added for Optimizepress/s2member?
