How to delete Cloudflare?

I just test cloudflare with netlify BUT i dont want use cloudflare.

I change NameServers back to netlify and i am always have cloudflare beacause i see in source code.
I deleted site from cloudflare.

How fix it?

If you’re sure you’ve changed nameservers in your domain registrar (and not in CloudFlare) to those of Netlify, they will be updated in some time. It might take around 72 hours in some cases.

I am 100% sure. I change it yesterday. Back to netlify nameservers. Maybe i wait more time.

Hi, @Anonymus2020. If you let us know the actual domain name which isn’t working, our support team is happy to research this to see what is happening.

You can post that information publicly or you can private message (PM) that to one of our support staff. I’ve confirmed that PMs are enabled for your community login. Please keep in mind that only one person can see the PM and this will likely mean a slower reply than posting the information publicly. Please feel free to reply to however you prefer though.
