Jetpack Error

I am trying to connect Jetpack to my word press site. when I got to connect I receive this error:

Error Details: The Jetpack server could not communicate with your site’s XML-RPC URL. Please check to make sure https://www.entertainmentunlimited.com/xmlrpc.php is working properly. It should show ‘XML?RPC server accepts POST requests only.’ on a line by itself when viewed in a browser and should not have any blank links or extra output anywhere.

when I go to the link and check it this is what it says:

XML-RPC server accepts POST requests only.<style>[Spam moderated]</div>

It looks like I’ve been hacked, but I don’t know where to go to remove that. Any ideas???

Also, we host on GoDaddy.
