I have two issues on my store.
First of all, when I try to register a new account, "Required parameter missing or invalid: customer" shows up like the below image.
Second, adding a new address in account detail can't be completed with an error massage "Province Not Valid".
I'm guessing that problems are caused since store language was changed from English to Korean.
Also tried changing store language to English again and putting US address into input box to add a new address, but not working at all.
Could you guys help me out?
