I can't use this plug-in

I active this plug from wordpress setting, but when use this show me this error :

{"status":"error","error":"The 'create_post' method has been removed from the Core controller. To use this method you must enable the Posts controller from WP Admin > Settings > JSON API."}

I achieved "nonce" , but when use this link :href=”http://SITE/api/create_post/?nonce=d7d622d2a7&title=Newpost%20Test&st­atus=publish”
