WordPress multisite is a great feature for those who run multiple blogs. Recently I was tasked to set up such a configuration on Dreamhost, only to find that multisite doesn’t play well when it comes to using subdomains (and by extension, external domains) in a shared hosting environment. According to the official documentation, you’ll need access to your Apache httpd.conf file for subdomains to work. For most shared hosting plans, it’s understandably not allowed. Fortunately for those of us on a budget, there are some workarounds.
