I have created three new blogs with MU:
blog1.subdomain.domain.tld
blog2.subdomain.domain.tld
blog3.subdomain.domain.tld
However, when I or anyone creates blog4.subdomain.domain.tld and above, we can't get them to appear.
The VirtualHost entry in apache's conf/extra/http-vhosts.conf file exists for blog4 and is exactly like that of blogs 1, 2, and 3 except for its name. Everything else in the options for blog4 are set the same as 1, 2, and 3 (except the name). Finally, I was also sure to click the activation link, but even that comes up as "Server Not Found".
Is there a default limit to the number of blogs you can create with MU? If so, how do I change it? If not, what else could be wrong here?
