  • WordPress Multisite support is NOT PROVIDED BY DREAMHOST.
  • If anything on your multisite installation is not functioning, you must troubleshoot it yourself or hire a developer.
  • Multisite is not for WordPress beginners. You should already know how to use WordPress before considering using Multisite.
