hello i have made an error and now my website is not pointing to Cloudflare. how can i change it back
I’d suggest you to write a ticket to your domain registrar about this and/or manage how to modify your domain nameservers in the domain registrar interface.
In short, you have to change your domain nameservers at your domain registrar and make sure they are pointing to the Cloudflare’s, the ones which were assigned to your Cloudflare account → you can double-check them by navigating to the DNS tab of Cloudflare dashboard for your domain name.
