Email notifications are disabled by default. To enable them, click the “Configure” link in the top-right corner of the widget and enter your email address in the “Periodically email logged errors to:” box. If desired, you can also change email frequency by selecting the minimum time interval between emails from the “How often to send email” drop-down.

Thank you, a very good and useful plugin for catching and fixing bugs. I bought a paid version, which still has convenient functionality. I also prepared a translation into Russian, which will help other users to use this plugin. Good luck)

Great and useful plugin


It is certainly useful and has a few options but installation is manual.  It doesn't have any display log option to view filtered out messages.  Email notification doesn't seem to work.



I'm not sure about those people complaining about no clean uninstall, I don't see how they could expect that given that there was no installation done by the plugin (therefore no "clean install" either)...


Quite Good but No Display full Log Option (or other filtering)


In spite of repeated support threads about it, this plugin doesn't limit to the log file size.  Twice it's used all available storage and caused a site to crash.   Today, a 100GB log file.This shouldn't be a fancy feature, it's basic best practice to code plugins in ways that don't crash sites.The widget itself is otherwise handy and convenient.  


Crashed site


Nice plugin! Makes it easy to keep up with errors.

Very nice to be able to push certain events to New Relic logs. I can even see Wordfence alerts and user logins coming in which is awesome! 

Great plugin!
