Thank you for giving some time to check my issue.
I have one site on siteground and I have setup Cloudflare from hosting control panel. I followed all steps as mentioned here in this video https://www.youtube.com/watch?time_continue=169&v=R6Ul2rHIUyg
But unfortunately, it doesn’t work for me. On GTmetrix, it still shows CDN = 0 in the yslow panel.
Can anyone help me with some hint to fix this?
