recently i've installed the latest RC and tried to set up a multisite on http://www.zimmi.cz. Everything went OK until i tried to access installed blogs on subdomains (try http://blog.zimmi.cz). It always returns error 403. I'v read a bunch of tutorials so far, none of them mentioning this problem. What might i have done wrong? Do i need to set up some DNS records? Thanks for reply.
PS: I installed WP to the root directory, subdomains are located in subfolders (meaning blog.zimmi.cz is located on zimmi.cz/blog but accessible as subdomain).
