How to place a subdomain in a folder for DLE?

Question

PHP

Good day! There was a need to create another language version of the folder in DLE. The main page opens fine, but the inner pages don't work - even from the admin panel in preview. From the beginning I thought that the problem was in the .htaccess of the main domain, but when I tried to expand the subdomain in the folder of another site, I ran into the same problem. Maybe someone faced similar, where to dig how to fix it?

The problem is most likely in the CNC - when the function is disabled in the script settings, the pages are loaded, but how to fix it?)
