I am using Paid memberships pro Version 1.5.7
My problem is after someone makes a purchase through paypal express, the confirmation page will display:
Invoice # on January 1, 1970
Membership Level: Test Level
Payment Method Membership Level Total Billed
And so the actual invoice is not displayed. The user does receive his membership, additionally, I can see the invoice in the memberpage of the user.
Thus, it appears that something is not being communicated, because the invoice # is not being displayed on the confirmation page after a payment.
I am contemplating just removing the invoice from this page in the PHP. Perhaps someone can help me solve this though, and keep the invoice in the confirmation page
