        root /var/www/wordpress.
        index index.php index.html index.htm;

        try_files $uri $uri/ /index.php?$args; }
}

location ~ .php$ {
        include snippets/fastcgi-php.conf; } location ~ .
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock; } location ~ .php$ { include snippets/fastcgi-php.conf.
