How to make a multilingual site on DLE?

Question

Internationalization and localization

Guys, I have a question, how to make English on DLE.
switches /eng/ and /ru/
I read an article by Pafnuty, but there was for DLE 9.4
in the admin panel you write the path, for example, if you press eng then the template is such and such if ru then the template is such and such
RewriteRule ^eng/(/?)+$ index. php?action_skin_change=yes&skin_name=theme_eng [L]
RewriteRule ^ru/(/?)+$ index.php?action_skin_change=yes&skin_name=theme_ru [L]
But in DLE 11.0 action_skin_change=yes&skin_name= this function doesn't work for some reason, maybe in dle 11.0 changed to another function? maybe something like this: action_template_change=yes&template_name=

Answer 1

I will say that index.php?action_skin_change=yes&skin_name= works in 11.
Go to the official demo and switch:
demo.dle-news.ru/index.php?action_skin_change=yes&...
demo.dle-news.ru/index.php?action_skin_change=yes&...
demo.dle-news.ru /index.php?action_skin_change=yes&...
