Did you move them off the screen where you cant see them any more it depends when you log in you can reset your UI for that char. but it resets UI everything or Did you close them then you can use the EQ button > (i dont know the path right now but your see a list of about 10 hotbars ) and select each hot bar to turn on/off
EQ Button > actions > in that menu Also, if there are hotkeys already set up to show/hide those hotbars, you may find them under Options > keymap (or something to that effect) > hotbars
