I have created menus (Appearance ---> Menu) and they are not showing up on my website. I am running the Kingdom Theme. Please help and keep in mind i am new to this. Thanks in advance!
Once you create the menu (in Appearence, Menu), you have to tell the theme to use that menu. That is usually in Appearance, Customize, which should then have a choice somewhere (depending on where the theme author put it) that you can specify a menu you built. Some theme's Customization let you directly create/change/specify a menu.
Just creating the menu doesn't apply it to the theme. You have to 'tell' the theme (through Customize) what menu to use (you can create more than one; and some themes allow you to have different menus in different places).
