WordPress scheduled tasks (WP-Cron) stalled

What it is

WordPress's scheduled tasks (WP-Cron) are stuck and haven't fired recently, so automatic updates, backups and scheduled scans may not be running on time — the same risk as having them disabled outright.

How to fix it

Set up a real system cron job (through your host) to trigger wp-cron.php on a fixed schedule — more reliable than WordPress's default, page-visit-triggered cron.
