In Recent list of my developed site using marinelli theme the more button info was ok for authenticated user but disappeared for anonimous visitors.
After some unsuccesfull debug activity, I decided that the problem were in permissions:
Recent list is a sort of content overview .
So checking permission to Access the content overview page for anonimous gave life to more button info at end of list also for visitors of www.difendisanta.it/drupal7_ch8.

Hope this help someone. Gianni
