I have run a single user install of WordPress for a couple of years, but recently decided that I would like to run one or more blogs on the same domain. So I took the plunge and set up a network following the instructions in the codex.
Installing the network seems to have worked fine. I set up a wildcard subdomain, which my host (xlhost.de) specifically offers. I modified the .htaccess for subdomains, and created blogs.dir, giving it 0755.
I went ahead and created a site as Network Admin, which all seemed to work fine, but am not able to get to the Dashboard for the site. The database tables for the site are created just fine, but the address won't resolve at all. I am assuming there's an error with the wildcard subdomain, or what else could it possibly be? How can I check if WordPress can use the wildcard subdomain? Should I contact my host?
