This error typically means that WordPress’s WP-Cron system failed to execute the scheduled task responsible for sending bulk emails through Noptin (noptin_send_bulk_emails).
Essentially, WordPress attempted to run the event but failed. This might result from a misconfiguration, conflict, or external limitation.
In most cases, this does not mean Noptin is broken. Here’s how to diagnose and resolve it systematically:
1. Confirm WP-Cron Is Enabled
Noptin relies on WordPress’ internal cron system. If it’s disabled, scheduled events won’t run.
Open your wp-config.php file and look for this line:
define('DISABLE_WP_CRON', true);
If you find it, change true to false or remove the line entirely:
define('DISABLE_WP_CRON', false);
Then save your changes and refresh your Site Health page. If the warning disappears, the issue was simply that WordPress’s cron system was disabled.
Pro Tip:
If your host disables WP-Cron, consider setting up a real cron job instead to trigger it periodically:
2. Verify Scheduled Events Exist
- Install a CRON management plugin, such as WP Crontrol (it’s free).
- After activation, go to Tools → Cron Events.
- Look for an entry named noptin_send_bulk_emails. You should see its next scheduled run time.
- If it’s overdue or stuck, click Run Now to trigger it manually.
- If it runs successfully, the Site Health error should disappear within a few hours.
- If it fails again, delete the event, and Noptin will automatically recreate it when the next email is queued.
3. Make Sure Your Site Can Loop Back to Itself
Go back to Tools → Site Health → Info and ensure there are no issues with “Loopback requests.”
Loopback requests are how WordPress triggers WP-Cron internally. If Site Health shows errors like “Loopback request failed,” it means your site can’t call itself to run scheduled events.
Contact your webhost, and they’ll help you fix this.
