Right now all of my content is available via http://www.domain.com/post-name/. I would also like to same content to be available via img.domain.com/post-name/. I have server a *.domain.com serveralias under VirtualHost in my Apache config and setup the DNS entry. I get the following error now: http://bit.ly/mORGOz
I've run through the Creating a Network doc without issue: http://codex.wordpress.org/Create_A_Network
Have I missed something, or do I need to install and configure the Domain Mapping plugin? Thanks!
