I have two different forms, both exactly the same except one is for free users and one is for paid using the PayPal add on. The forms are using PayPal and User Registration. Using two PayPal accounts, one to receive payments and one to test sending payments, it shows the payment was received on PayPals end after submitting the form, however I get no email notification, the user and the post does not get created. This was working before with other forms we are using for a different purpose, but I retested those today and now they are no longer working. Any ideas on what is happening?
