WordPress multisite error 404 on Network Admin and other links

Hi I have a fresh install of WordPress in my domain, configured for multi-site. Subfolder setup.

the thing is, Network Admin on the upper right menu has this link http://example.net/wp-admin/network/ and returns error 404… I can manually type it to http://example.net/subfolder/wp-admin/network/ and works fine.. other links like Add New has this problem too…

I’m not good on .htaccess but I think the problem is there…

can you check this please

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) home/content/70/10156275/html/example.net/subfolder/$1 [L]
RewriteRule ^(.*.php)$ home/content/70/10156275/html/example.net/subfolder/$1 [L]
RewriteRule . index.php [L]

also, not sure if this helps but my wp-config.php has this

/* Multisite */
define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', true );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'example.net' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

been searching google for 2 days now and can’t fix this…
The problem is the subfolder is somewhat omitted in Network Admin and some few..
