Hi,
I'm having trouble in my check-out proces.
In the process the user can either login or register.
If the user logs in and has an account with 3-way authentication enabled, the user end up on a wrong url after the 3-way authentication.

Then the process ends up in this url: www.e4o.eu/webshop/winkelwagen/checkout/showblock?tmpl=raw
where it should be www.e4o.eu/webshop/winkelwagen/checkout/cid-2
resulting in a blank page.

Is this a known bug? Or can I do something to change it?
Best gegards ,

Solved it...
In the checkout steps I put the login/registration in a separate step.
Before the invoices address was in the same step, now that one is in a new step after the login
