1) I am trying to configure the fields for the Address of a registered user, but I am not able to manage the First Name, Last Name and Email of the form, any reason why I am not able to manage and hide them?
2) Also, the City field is appearing before the Address and City Code, and I need it before because is the correct order here in Portugal.
1) They can not be configured, since they are required. Why would you like to hide them?
2) In Language Configuration>Edit
just change the City string resources value to "Zip/postal code" and vice-versa
