Hello!
I have configured the Jstore to make an order without registration (with Guest accounts). If I'm trying to make an another order (when registered user is logged or from another browser) I'm getting the following error: "A user with the same email address already exist. Please login or register with another email!". This means that I have to login on Joomla if I want to make an another order. I have tried the Allow Duplicate email plugins, but still I'm receiving the error. "A user with the same email address already exist. Please login or register with another email!".
Thanks!
