Enabling and Configuring Multisite Q: Why am I forced to use subdomains on older WordPress installs? A: Sites older than 30-days will see this warning. The reason is subfolders in Multisite could conflict with page URLs that already exist. Also /blog is added to the main website’s blog permalink structure, which could cause existing blog posts to 404http://codex.wordpress.org/Create_A_Network
