At the moment my 'Categories' are not visible in the Homepage of my blog. The URL is http://www.timvanorsouw.com/blog
Trying to add the Categories @ Appearance-->Menus results in this quote: "The current theme does not natively support menus, but you can use the “Navigation Menu” widget to add any menus you create here to the theme’s sidebar."
So I tried using the 'Navigation Menu' widget to add the menus to the themes, but when I do this I'm being sent to the same 'Appearance-->Menus' screen and ofcourse the same quote (The current <...> theme's sidebar". comes up.
How can I make my Categories visible for visitors?
