Your screenshot says there’s 1 issue, but it doesn’t say what it is.

This is the problem after enabling Cloudflare and bots fight mode.

Which Bots Fight mode? If you’re on a free plan, the regular Bot Fight mode should be safe, but anything more will probably block Google’s good bots.

Are you seeing anything in your Firewall Events Log that looks like Google bots being stopped?
