2. In the left-hand pane, click Settings, and then click Heartbeat Control. The Heartbeat Control configuration page appears.
3. In the Control heartbeat locations list box, select where you want to disable or enable the WordPress heartbeat:

• To disable heartbeat functionality entirely, select Disable everywhere.
• To disable heartbeat functionality on the dashboard, select Disable on dashboard page.
• To enable heartbeat functionality only on post edit pages, select Allow only on post edit pages.
