It looks like your site is hosted at WordPress.com and is a little different. They do have their own support forums as well located here: https://en.forums.wordpress.com/

I can tell you though just from looking, it may appear that you have not set a menu for that. They do provide some documentation on how to do this as well and can be found here: https://en.support.wordpress.com/menus/view-all/#1-create-a-custom-menu

Hope that helps.
