Yep, I just realized that I needed to update the eStore plugin (the eMember integration part) so it does’t put the email in the database after the purchase. This is necessary now that the WordPress user integration feature has been implemented in eMember.
I have sent you an updated version of the eStore plugin which should resolve this issue. I couldn’t fully test this fix as it’s pretty late and am going to bed… I just wanted to give you something so you can keep working on your project. Let me know how you go.
