Right from that moment on, something changed in the uptime performance monitoring service that I use, namely NewRelic Synthetic.
NewRelic always monitored the cached pages of my websites. But after the WPO update to version 4.0.0, NewRelic suddenly started monitoring the non-cached web pages. I could see that from the fact that the loading times in NewRelic had suddenly increased by about 500ms.
I also monitor the keyword “Cached by WP-Optimize” with NewRelic and since the 4.0.0 version, NewRelic can no longer “see” this keyword, even though it is in the source code, at the very bottom, of the monitored web page, as normal. So cache is working!
Has something changed since version 4.0.0 that could have caused NewRelic to no longer monitor the cached pages, but instead the non-cached pages?
