← Part 1: MainWP Introduction Part 3: MainWP User Interface → MainWP requires two components:
  • MainWP Dashboard - Install on a dedicated WordPress site that controls all other sites
  • MainWP Child - Install on each WordPress site you want to manage
Install MainWP Dashboard on a clean WordPress installation rather than an operating site. This eliminates plugin conflicts.
MainWP has no site limit. Check the System Requirements to verify your server can handle your planned number of child sites.
