This plugin allows developers to debug PHP errors.
Features for Developers
<ul>
<li>You can get call stack trace when PHP errors are triggered.</li>
<li>This is particularly helpful in finding errors that are triggered by the WordPress deprecation and 
doing_it_wrong code. These errors are reported in the WordPress core instead of at the location 
where the incorrect usage actually occurs. </li>
<li>You can set the error level from the Settings page, the default is trap Notice and Deprecation errors</li>
</ul>
Additional Features
There are no additional features supported by Simple Error Handler. The code is simple, small and well documented, 
so you can use it as a starting point for your own error reporting or logging plugin.

Simple Error Handler

A simple plugin that reports the call stack trace when PHP errors occur.

This plugin sends you an email notification whenever a fatal error (or other error level, configurably) is detected on your site.
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.

Fatal Error Notify

Great plugin

Thiss plugin is useful but won´t work on certain installs, although this could easily be fixed with some enhancements.

useful plugin but could be improved

I used Fatal Error Notify on a site that kept crashing and I couldn't find out what was going wrong.  The plugin emails the PHP error message and that helped me track down the issue. 

Can be a real lifesaver

Just came here to say that this is an amazing plugin and it's extremely helpful during troubleshooting.

keep up the good work!
