Yesterday I switched the nameservers for my website from NameCheap to CloudFlare so that I could take advantage of their CDN / HTTP/2 features.
Now I just made some changes to my website and tried reloading it, and I got the message "You do not have a CNAME set up for your domain."
As you can see from the image below, CloudFlare did seem to copy over the CNAME record correctly from NameCheap.
Note that the website did seem to reload correctly and does seem to work fine, even though this error showed up.
What should I do?
