Hi,

In my multilanguage site DNN 7.3.4 when I have a culture neutral page (even empty one), it show correctly  using the link of default language http://www.pcam.com/en-us/Support/Knowledge-Base

but show an error if I go on a another installed/activated language 
http://www.pcam.com/it-it/Support/Knowledge-Base

I don't know if it's a normal behaviour as it page is really nonexistent, but if is it, the problem is that the language selector seem don't recognize the fact .....
