I've a custom skin that uses DDR Mega menu. All is right if I browse the site using a logged on account. If I browse it as anonymous user, the menu doesn't show submenus.

I've checked that the emitted html contains all menu data, and that the js and css files related to the menu are downloaded by the browser (in fact firebug reports that all page downloads are ok). So it seems that all resources are loaded by the browser, but still the menu is not expanding.

Any idea?

thanks
