Just setup a new server and have installed mod_pagespeed.
It only seems to be working on html pages, not PHP. Below are the headers for two simple pages and apart from the Vary: Accept-Encoding I can’t see any differences. Can anyone help me to get this working?
Below is a php page where you can see pagespeed is not working

Are you seeing anything different if you access your service directly? According to the headers you’ve provided this content is being proxied via CloudFlare and these headers are coming from their service sitting in the middle
So after trying everything I can think of I think it is the Grav CMS I am using which is injecting the header.
I have yet to find out how to stop this though
