Dashboard on multisite/subdomains not working

Hi,
I am trying to figure out how to use multisite feature with not much success. I will use dummy site URLs below.

Let me start with description of folders as provided by webhosting:

• -root/www – > this is root of main site, where WP has been installed, support.info
• root/subdoms/hu -> this is root for subdomain hu.suppport.info
• root/subdoms/en -> this is root for subdomain en.support.info

My current .htaccess in root/www has this inside:

RewriteEngine On
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
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

wp-config in root/www has this:

define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', true);
define('DOMAIN_CURRENT_SITE', 'siapodpora.info');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

in root/subdoms/hu/.htaccess I have:

RewriteEngine On
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
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

in root/subdoms/hu I have index.php with some code – no WP related.

When I try to open dashboard for any of the subdomains, I receive 500 Error. When opening site as normal browser, not trying to open dashboard, site reacts and index.php renders.

Is there a way I could setup WP to work in this environment, without having WP installation in each of subdomains folders? For some reason hosting provider has it organized as this.

Any help appreciated.
