Why Aren't WooCommerce's Action Scheduler Tasks Running?

Why This Happens

WP-Cron isn't a genuine background process running independently on the server — it's triggered by an incoming page request checking whether any scheduled task is due and, if so, running it as part of that same request. A store with very little regular traffic, or one where WP-Cron has been explicitly disabled (a common hosting recommendation in favor of a proper system-level cron job, for better reliability and performance) without that system-level replacement actually being configured, can leave tasks queued indefinitely.

Common Causes

• Genuinely low site traffic, meaning WP-Cron's page-visit trigger simply doesn't fire often enough to keep the task queue moving promptly.
• DISABLE_WP_CRON set to true in wp-config.php without a real server-level cron job configured to replace it, which some hosts set by default expecting the site owner to configure the replacement themselves.
• A caching plugin serving fully static pages for anonymous visitors, which can prevent the WP-Cron check from firing on those cached page loads, reducing effective trigger frequency further.
• A stuck or failed task blocking the queue behind it, in some Action Scheduler configurations, though this is less common than the more general triggering issue.
• A very large backlog of overdue tasks that accumulated during a period when cron wasn't running, which can take a while to fully clear even once triggering is fixed.

How to Fix It

1. Check whether DISABLE_WP_CRON is set in wp-config.php, and if so, confirm a real server-level cron job is configured to call wp-cron.php regularly instead.
2. Set up a proper server cron job (typically every 5-15 minutes) as a more reliable alternative to relying purely on page-visit triggering, regardless of current traffic levels.
3. Check WooCommerce → Status → Scheduled Actions for a backlog of overdue tasks, which confirms whether this is actually the issue.
4. Monitor after the fix to confirm the backlog clears and new tasks run on schedule going forward.
