XML-RPC is not responding correctly ( 200 )

Error: XML-RPC is not responding correctly ( 200 )

It looks like XML-RPC is not responding correctly. Please make sure XML-RPC is turned on for your site and is set up to respond to all content types. You can test this yourself by running the following command from the command line:

curl -A 'Jetpack by WordPress.com' -d '<methodCall><methodName>demo.sayHello</methodName></methodCall>'

The answer should be:

<?xml version="1.0" encoding="UTF-8"?>
<methodResponse>
  <params>
    <param>
      <value>
      <string>Hello!</string>
      </value>
    </param>
  </params>
</methodResponse>

Hi,

Since I started using Cloudflare [Free] my Jetpack plugging [Free] doesn’t work. In theory, it’s connected but it doesn’t show stats and on the mobile app it doesn’t synchronize anything.

I tried all solutions available online, but nothing works. Could you please have a look and help me?
