[Plugin: Advanced Menu Widget] Only works when logged in

Hi, the widget looks great, but it only shows the menu-items when I’m logged in. I can’t find the setting that causes this. Am I missing something?

When I’m not logged in the source does show the conatiner of the widget <li
id=”advanced_menu-2″ class=”submenu widget-container widget_advanced_menu”><ul
id=”menu-hoofdmenu” class=”menu”> but not the links. When I’m logged in the menu-links show up.
