Hello!
The problem is simple. Look here for how the demo of your theme shows the “my account” page, and please look here to see how it looks like in my implementation.
The billing address (“adresa de facturare”) is ok, it can be edited, however the shipping adress (“adresa mea”) cannot be edited. This happens for any type of user, not only admin, but also to a simple customer that hasn’t filled anything on the website.
Credentials below. Thanks again 🙂
