Help! I've lost the home option on my menu!

Hi,

I was trying out different menu plug-ins to try to get a sidebar menu that included categories. I eventually found one, but in the process I have lost the home option on my main menus! I deactivated all the plug-ins that dealt with menus but the home option is still gone. I have the fifteen theme, Custom CSS Manager and a child theme. My URL is . I’ve tried everything I know how to do.
