menu link disappeared

(excuse my basic english)
I have found that in the list of the navigation menu the root voice related to ???
- Configure DAV Authentication
- Manage SVN Repositories

is disappeared, i mean there is the "+" (plus) sign to expand submenu voices but the root voice isn't shown.

I know it's not an urgent bug issue, but it's not nice to see ... maybe it could happen with somethin else ... who knows ?

I have not done anything special, that i remember. I've just added virtual servers, normal servers and routine tasks. No upgrades or 3rd part applications ...
