The site does not open without choosing a language. Is it fixable?

Question

Joomla

I bought a template, but it has two languages.
I need one language.
When entering the main page, you must select a language.
All edits were made on the site in only one language .....
How to fix it so that the site opens along the domain.ru path already with the selected language.
And now we get a working version of the site domain.ru/index.php/en/
