How to make a post template with pagination in multisite mode?

Question

WordPress

Wrote a template. Wordpress works in multisite mode. Websites are like directories. It was necessary to make a multilingual site. The URL /ru/ loads a site with a Russian template.
I can't figure out how to display posts with pagination.
Another blog is added to the yurl. I tried to add a cycle to index.php, archive.php but the 404 error page pops up all the time. The main page is static and the home.php file is used
The site itself is gaininspain.acspro.ru
Guru tell me how to fix it.

Answer 1

Sorry. I'm a fool, I hurried))) There was a slider in the header and did not reset the cycle. That's the whole trouble ((((You need to sleep sometimes ((((
