Hi songdogtech - DesktopServer (serverpress.com) is a virtual server that resides on your computer and can be accessed from your desktop web browser via a fictitious, pseudo top-level domain name: .dev (in example, http://www.example.dev). It does require administrator access and works similarly I understand to xampp or wamp in allowing you to work directly on your desktop prior to uploading to your host.
As explained in my first post I am completely new to using WordPress although I have a Dreamweaver background. I decided to disable DesktopServer and setup things up using XAMPP (Mac). I used a fresh copy of WordPress 3.9.1 and TwentyFourteen, but once again found the 'Manage Locations' tab still missing from the Appearance > Menus pane. Has Manage Locations been moved to another area of 3.9.1 or am I doing something dramatically wrong?
