When trying to go in the post advanced edit mode, there's a javascript error that prevents the funtionality to work properly. However, you can still go advanced by assigning an empty object value to the PATHS variable using the console: var PATHS = {};
The settings link is between "Welcome, mschwartz." and "Log out" at the top of the page, but the text for the link is missing. I can click on it by moving the mouse until the mouse pointer changes to indicate it's over a link,
