  User personal information cannot be changed
  ## Expected Behavior
  
  User can change its personal information at any time using Settings page.
  
  User should only be able to change their first and last name. The E-mail field should be grayed out.
  
  ## Actual Behavior
  
  Form fields are filled with user data but there is no way to change them. User cannot modify these fields and there is no "Save" button available.
  
  ## Steps to Reproduce the Problem
  
    1. Go to Settings page.
    2. Open "User data" section.
    3. Done.
  
  ## Additional comment
  
  Consider changing the name of the section from "User data" to something else.
