Unlike traditional uptime monitoring services, which will only notify you if your entire site is down, this plugin can notify you when an error is detected on any page or process on your site. Automatic plugin and theme updates often introduce problems that you aren’t aware of until they’re reported by your visitors. Fatal Error Notify lets you address these issues as they occur and before they cause significant problems. ## Screenshots * [[ * Admin configuration settings * [[ * Example email received when an error has been reported ## Installation Install it just like any other WordPress plugin: Either: Upload the plugin files to the `/wp-content/plugins/fatal-error-notify` directory. Or: Install the plugin through the WordPress plugins screen directly. Then: 1. Activate the plugin through the ‘Plugins’ screen in WordPress 2. Use the Settings->Fatal Error Notify screen to configure notification settings ## FAQ ### How does the plugin send error notifications if my site is down? Fatal Error Notify hooks into PHP’s “shutdown” function to send notifications right before the page stops loading. Even the dreaded “500 – Internal Server Error” still triggers PHP’s shutdown actions. Even if your site is completely offline, in most cases this plugin will be able to detect the error and notify you. ### What’s in the Pro version [Fatal Error Notify Pro](https://fatalerrornotify.com/?utm_campaign=fatal-error-notify-free&utm_source=wp-org) includes several additional features, like Slack notifications, the ability to hide the plugin settings, multisite support, logging of recorded errors, out of memory handling, the ability to pause individual notifications, and more. Fatal Error Notify Pro also includes integrations with Gravity Forms, WooCommerce, WPForms, [WP Fusion](https://wpfusion.com/?utm_campaign=fatal-error-notify-free&utm_source=wp-org), and WP Mail SMTP and can send notifications when errors are logged in those plugins. ### Can I exclude specific errors? Yes, you can use the filter `fen_ignore_error`, like so: ``` function fen_ignore_error( $ignore, $error ) { if( $error['file'] == '/home/username/public_html/wp-includes/class-phpass.php' ) { $ignore = true; } return $ignore; } add_filter( 'fen_ignore_error', 'fen_ignore_error', 10, 2 ); ``` The `$error` variable is an array containing: * `$error['type']`: (int) The PHP [error code](http://php.net/manual/en/errorfunc.constants.php) * `$error['message']`: (string) The error message * `$error['file']`: (string) The path to the file that triggered the error * `$error['line']`: (int) The line number that triggered the error ### Does it support WP CLI Yup, you bet! You can update the plugin settings using WP CLI, for example to set a default list of error levels, or a notification email address. The two methods are `get_option` and `update_option`. For example: ``` wp fatal-error-notify get_option slack_notifications ``` Will tell you if Slack notifications are enabled on the site. ``` wp fatal-error-notify update_option notification_email email@domain.com ``` Will update the notification email for the site. You can also update options on multiple sites using xargs: ``` wp site list --field=url | xargs -n1 -I {} sh -c 'wp --url={} fatal-error-notify update_option notification_email email@domain.com' ``` If you are updating options that are stored as arrays (for example `levels` or ` plugins`) you can use JSON-formatted values. For an example, use `get_option` first on the field you are trying to update. ## Reviews ![](https://secure.gravatar.com/avatar/9786181f2ac82df1c2b05de1899533eadab7a16b5e6f7462d0c11f6abe6af6bd? s=60&d=retro&r=g) ### 󠀁[You need the Pro version](https://wordpress.org/support/topic/you-need-the-pro-version/)󠁿 [Li-An](https://profiles.wordpress.org/li-an/) March 10, 2026 4 replies Last version adds notifications for some EXIF problems.

The Pro upgrade is also really worth it and the support from the developer is some of the best I have ever experienced. The plugin really helps you pinpoint and diagnose errors, often well before you would notice them visually on the frontend of the site. Getting the error stack trace from the plugin also really helps you get better support from other plugin devs when their plugin has an error on your site. Highly recommended. Dale. ![](https://secure.gravatar.com/avatar/d0c02370afdabf50b520d968bcf12911f7dd65a9fe8ba8984575277244621127? s=60&d=retro&r=g) ### 󠀁[BEST PLUGIN – PERIOD](https://wordpress.org/support/topic/best-plugin-period/)󠁿 [Steve](https://profiles.wordpress.org/aksteve/) May 30, 2023 1 reply Shame on WordPress for notifying us of fatal errors but supplying no information. And HUGE KUDOS to the creators of this plugin who picked up the slack. This plugin will let you know WHERE the fatal error occurred, which is vital when troubleshooting. Why WordPress doesn’t do this is a mystery. WordPress just get less and less user- friendly. It’s plugins like this that help make WordPress better. HEY WORDPRESS – TAKE A LESSON FROM THIS PLUGIN. This is a HELPFUL plugin and it is USER-FRIENDLY. Unfortunately, all things that WordPress is slowly no longer being….
