Not sure if this has changed in XF 1.1, as I am still running on XF 1.0.4 and see this happening on my own forum. Browsing the Forum as a Guest, so NOT being logged-in. When there is no thread showing within "What`s New" (especially on Forums which do not have that much activity, as threads within "What's New" disappear after 2 days), then the Link for "All Recent Threads" is not showing up. So clicking onto "What`s New" is showing the message "No Results Found" and the Link for "All Recent Messages" is not available at all. Would be better to include the Link for "All Recent Messages" within the Navigation-bar, so that it is always possible to click onto that link.
