Site within the site how to implement?

Question

CMS

Hello everyone, yesterday I tried to put a site in different languages
​​on the Vii Engine, found files with different languages ​​on the Internet, and then such a moment, adding these files - the site stops working. The best solution is to do it on the site and add the "English, French, Russian" button, it seems to me) the problem is, the site on the site says it's done, the address is like this localhost / en /, it would seem that you sit and translate a bunch of files , but the files are redirected during any action to the root of the site, which makes these actions useless, does anyone have experience in such matters, like a site within a site?
Guys, yes, if suddenly someone wants to help not only with a word, but also helps to do and explain, then we could discuss the details on what conditions)
