Allows for more details reporting for the “Redirection” plugin by John Godley. 
This plugin will not do anything for you without using the Redirection plugin 
to handle your 301 redirections. This plugin was built to fix a gap in the 
reporting which the Redirection plugin has.

Redirection Reporting

Allows for daily reporting for redirected requests.

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!
