links not working when logged in

Hi

I have what I think is a strange issue

if you look at http://wsmfhs.org.uk/

there  is a block that contains three nodes

Latest News

Latest Research

New Surnames.

These contain links to the full article.

If I am not logged in the links work but if I am logged in they dont.

ie “February monthly update” is a link if I am not logged in but isn’t when I am

Has anyone any ideas why?

thanks

Ian
