Sorry I do not understand how to do it. I tried everything and my host, too, the whole day but we still go back to 520 or broken website.
Can I go back to my host, instead of using Cloudflare? It's a bit complicated to me. Maybe if I change my nameservers back to Fastmoose's, the website will be fixed. My new problem will be how to connect it to ezoic, like the first time.
