Today I got a message from a member of my website that has bought a product a few weeks ago. Now he wants to buy a subscription, but he gets the following error message:
"This email is already registered"
The form does not allow him to continue and order.
I use Gravityforms + the Paypal add-on and the user registration add-on. On the product form, after a Paypal payment has been received, the user registration add-on adds the user to the database and sets the user role to "product x buyer". The form + the user registration add-on for the subscription adds the user and sets the role to "premium member". But apparently, it is not allowed for existing users to order and be registered again.
How can I solve this?
