Hello,
One of my customers pointed me on this bug:
When registering at checkout there is no check if the username already exists.
When I choose to register myself and the username already exists I still can place the order.
On the "thank you page" there is a notice "Username already exists", but the order is processed.
I think it should be as follow:
- When registering at checkout AND a username OR an e-mail address already exists the order is NOT processed
- the customer gets a notice so he can choose another username / email address OR login if he remembers his login details.
I hope this is just a simple fix and there will be an update for your fantastic component.
