When logged in as a normal user(https://host.com/zimbra/mail), clicking on Documents and then on "New Window" opens a new window to this URL:
The URL results in a 404 error. Removing the extra / so that the URL looks like this:
Successfully renders a notebook page (which in my case is empty because there is nothing there yet).
This is on a just upgraded 4.5.6 NE from 4.5.5 NE edition.
Looking around the forum and bugzilla the only thing which looked "close" was this: http://www.zimbra.com/forums/adminis...nts-error.html but I am not sure it is the same problem.
