Почему не подключаются стили для подпапки мультисайта на WP?

Настраиваю мультисайт на WordPress. Основной сайт встает нормально, доп. сайт должен быть в подпапке. HTML доп.сайта загружается, стили, js, картинки нет - в консоли 404 на все эти ресурсы. На тестовом хостинге все работает нормально. На нужном мне сервере нужно прописывать конфиги для домена, в которых не разбираюсь.

Вот мой конфиг, взятый с аналогичного сайта с того же сервера, разрабатываемого по аналогичному ТЗ:

        include fastcgi_params;
    }
    return 301 https://$host:443$request_uri;

Вот мой .htaccess, но не думаю, что проблема в нем:

RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
