I have changed my name server to cloudflare but since i changed it my website stopped working is now more than 24h my site still display the cloudflare error a blank page with (not found) after then changed back to my old name server which is dreamhost but still my site has not been recovered my site still show until today (not found) my website is would really appreciate your helps.
Your domain currently does not point to Cloudflare. You will need to contact your host if you have any issues.
Then you might still have the old IP addresses cached which is a DNS propagation issue. But at this point Cloudflare is not involved anymore.
OK you were right i removed cloudflare from dreamhost website, and now the site works again thanks
