Because of potential dangers that could happen while in debug we’ve removed this as a standard selection model. There two methods to still get debug though. First is to schedule a task as simply debug. This is probably easiest. Second method is to enable hidden menu and choose which key sequence you want to get back to menu. At boot it will ask for this key sequence. After pressing that key sequence you will receive a login prompt. Type in a valid fog GUI login and pass and it will display the menu with debug as we are all so used to. Hope this helps.
