does not activate

Great plugin!

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!
Amazing toolset, well crafted

Just came across the Perfops One Suite by chance and I have to say: Amazing!
Well coded, well maintained and an amazing feature set. I wouldn’t run any of our projects without it anymore. We use it with Datadog as Logger and I am really impressed by acually every aspect.
The Decalog SDK is a real gamechanger for plugin / theme development on your own platform when using Decalog.
Thank you very much Pierre. This is one of the examples why WordPress and OpenSource rock 🙂
Great Help

The debug log file was empty, and yet an error 500.
I just install this plugin and he catches every call just before the crash, really simple to use, and very useful.
