Now I get an error page when I click on communities from the dropdown menu. Is there a way I can reinstate this main Community link so it works properly again?

There are also a number a pages that I can't view but have created. When I try to add new pages to a new Community main page (that I created after I deleted the original by accident) link it says this page (new local community pages) already exist.
