General Settings – Notification Options

  • Notification – Email: Pretty straightforward— this is the email address we’ll send notifications to. You can optionally enter multiple email addresses separated by commas.
  • Notification – From Email: This is the “from” email address for the notification emails. Leave blank to use the site’s default admin email.
  • Test Crash Notification: You can click this button to trigger a test error. You’ll be notified by email and Slack (if enabled).
  • Disable Notifications: You can check this box if you’re using Slack notifications and would prefer not to be emailed.

General Settings – Error Levels

  • PHP Error Levels To Notify: These are all the possible error levels in PHP (descriptions here), but in most cases you’d just want E_ERROR checked, as this is a fatal error that takes your site offline. E_WARNING can also be helpful but some plugins trigger warnings that don’t necessarily indicate a serious problem.

General Settings – Plugin Errors

  • Plugin Errors to Notify: Depending on your installed plugins, Fatal Error Notify gives you options to receive notifications when any of these plugins trigger a non-fatal error.

Stealth Mode

Stealth Mode is a great feature if you’re using Fatal Error Notify on sites you’ve built for clients, and you don’t want them disabling the plugin or changing the settings.

Add one or more administrator-level users to the select box, and the plugin will be hidden from everyone else.

Slack Notifications

Instead of (or in addition to) emails, Fatal Error Notify can post to a Slack channel when an error occurs. Enter a Slack channel name, and generate a webhook URL and paste it in the box.

You can configure error levels for Slack separately from email notification levels.

Paused Notifications

Notifications sent by Fatal Error Notify will include a link to pause that specific notification. Any paused notifications will show up on the Paused Notifications tab.

You can check the box for Un-pause and save the settings to un-pause a specific notification.

Error Log

Error Logging can be enabled from the General settings tab.

Once enabled, you can view a table of recorded errors, filterable by severity and plugin which triggered the error.


Fatal Error Notify Pro can be network activated on WordPress multisite, and then it will report on errors on every site in the network.

To do so head to Network Admin » Plugins » Add New, and install and network activate Fatal Error Notify. The settings will be found at Settings » Fatal Error Notify in the network admin settings menu.
