Wrong URL

[Minato2016]

Hello dear, please help us to make detailed url.
Example: domen.com/forum/sub-forum1/sub-forum2/sub-forum3/topic-f13.html

At the moment all forums replace each other in the address bar of your browser. If sub-forums is greater than 1 then the url is: domen.com/sub-forum1/topic-13.html and if you go into a subforum, then the url is: dome.com/sub-forum2/topic-13.html and that I had was: domen.com/sub-forum1/sub-forum2/topic-13.html.
