I was installing wordpress MU blogs. It is working for subdirectory but it's not working for subdomain. The blog on subdomain is created but cannot be accessed with the url, but I can see that it has been created in Admin panel. I am not getting what is the problem is it wildcard dns or Virtual host problem, I am using shared hosting how can I config the files then. Pls tell me if anyone knows how can I fix this problem.
I hope you are in Linux server if so talk to your host support and tell them to enable wildcard dns for your domain. Your problem will resolved. You can also see mu.wordpress.org for more help
