This plugin provides a simple but powerful function for developers and site administrators. It automatically captures critical PHP errors (fatal errors, parse errors, etc.) that would otherwise take your site down silently.
Instead of having to check server logs, you receive an instant notification via a webhook to a service of your choice, like Slack or Discord. This allows for immediate action and faster debugging.
The setup is minimal: just add your webhook URL on the settings page, and the plugin takes care of the rest.

Wonderful Webhook Alerts

Get real-time notifications for PHP fatal errors sent to your webhook (Slack, Discord, etc.). Never miss a critical site issue again.

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with an automated email.
But sometimes the message bothers people who don’t know how to handle with it and how to fix the bug which causes the crash.
With Custom Recovery Mode Email now you can choose the right recipient email of the person who can deal with it.
Optionally you can also set Email and Name sender.
