Wordpress wp_remote_get() problem

Hello guys, I have problem at wordpress. Installed Betheme wordpress and after I tried to use demo content. Had that massage.

WordPress function wp_remote_get() test failed. Looks like your server is not fully compatible with WordPress. Contact your hosting provider. Error: cURL error 51: Unable to communicate securely with peer: requested domain name does not match the server’s certificate.

How can i set this up?

Make sure you are visiting your site via http://yoursite.com/wp-admin and not https:// else contact the person who made the theme/script.

If it is a permission error then WordPress function wp_remote_get() may be disabled on the free hosting service, upgrade to premium for $3.99 and it will work then.

Thank you sir for your reply
