Error when selecting Categories

although I have at least one listing linked to every category I have set up (it is for demo purposes) - when I click on any of the categories I am getting an error message that reads "Sorry, we can't find the content you're looking for at this URL. Please try selecting a menu item from above or to the side of this message to get where you'd like to go."

I AM FINDING USING THIS PLUGIN SO FRUSTRATING COMPARED TO OTHERS THAT I USE
