I have a tab on the homepage that should read iMatter and under that there should be 4 submenus. I see it correctly when I am logged into the admin console. However when I go to our website, I don’t see the submenus on the live page http://www.laurenshouse.org
This is not a support question for this plugin. It does not alter the front end menus.
The only admin menus you can toggle with this plugin are in the Network->Settings menu accessible via the Network dashboard. And that is not what you are looking at there.
