in order to return a custom page instead of the standard 404 page, I personalized the .htaccess file to direct users to page /uk/notfound.html when accessing unexisting pages.
As you may see by clicking on the dummy http://www.virtualtags.net/uk/goofy.html
url, the page returned is the one in the uk directory (you may check the one in the father directory at http://www.virtualtags.net/notfound.html
that is quite different from the one at http://www.virtualtags.net/uk/notfound.html
Yet the mens items, albeit reporting the fields in the /uk/ site, point to pages in the father directory, sometimes finding nothing, like in the Blog one in the info menu.
I think this is a bug in handling the <base> direction but please let me know how I may cope with that.
