the blogs are virtual, you do not need to place any files anywhere.
If you picked subdomains, then yes – you need wildcard subdomains set up.

Check the “before you begin” section.
Apache must be configured to accept wildcards.
Open up the httpd.conf file or the include file containing the VHOST entry for your web account.
Add this line:
ServerAlias *.example.com
So i should add ServerAlias *.example.com in my .htaccess file?
In the DNS records on your server, add a wildcard subdomain that points to the main installation. It should look like:
A *.example.com
I host at one.com so should I in dns-settings add ex. blogg.fiddeandersson.se and value A and in host/ip i set fiddeandersson.se?
Then it should work or?
So i should add ServerAlias *.example.com in my .htaccess file?
No. It says quite clearly:
“Open up the httpd.conf file or the include file containing the VHOST entry for your web account.”
If you cannot access this file, ask your webhost for support.
Okay, but i was looking below DNS-Settings at my webhost and find that *.fiddeandersson.se Type: A Value: One.com Network Active: Yes
and it’s that information that should exist right?
So how do I create a sub-domain then, just add a page from the super admin area?
Thanks for your support.

Add a new site, not a page.
Super Admin -> Sites -> Add a new Site.
Okay, sorry write wrong, but when i created blogg.fiddeandersson.se
i get an internal server error, is that something more you need to do to get this work?
Yes.
Ask your web host support team about wildcard subdomains,. they need to support it at the server level, not just in the dns records.
