I am setting up a new multi-store Magento 184.108.40.206.
If the customer wants to register a new account during the order process (onepage-checkout), the account won't get created in the DB. The order getting placed neatly but not the customer account itself.
No errors or exceptions are thrown concerning this issue.
But when I create directly an account in the frontend without processing an order, it works.
I am using a custom template. Apparently it don't touches the process. Aswell other extensions, as far as I can say.
Does someone have perhaps a clue to look for or an idea what could cause this issue?
