9. WP Cron Has to Be Enabled

Although, WordPress manages a number of routine tasks such as publishing posts, backing up, or checking for updates, this task is managed by the Cron job system. The system is a unique technology used by servers to manage scheduled tasks or recurring events.

WordPress Cron systems are depended on by plugins to perform tasks, but sometimes they keep most resources to themselves.
