I am receiving this error when configuring page settings, "Error: Landing page not found."
The reason for the error was because we are moving away from serving SSL and landing pages directly from our server. We now require landing pages to be served from a Cloudflare account. With this, please add your domain to Cloudflare.
Here is how to do it ~> https://www.youtube.com/watch?v=XQKkb84EjNQ
Then configure your domain's DNS CNAME record as usual via CloudFlare DNS settings.
Please enable the Proxy mode (Orange cloud icon).
Then set your Encryption mode to “FULL”
