Problem in author page

Hi,

I have a problem with your plugin, cause in the author page appears this message

Warning: get_headers() [function.get-headers]: https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /home/mhd-01/www.robadasocial.it/htdocs/wp-content/plugins/social-autho-bio/social_author_bio.php on line 1196

Warning: get_headers() [function.get-headers]: This function may only be used against URLs in /home/mhd-01/www.robadasocial.it/htdocs/wp-content/plugins/social-autho-bio/social_author_bio.php on line 1196

Join my Circle on Google+

instead of the Social Author Box. This is the website:https://www.robadasocial.it

How can I fix it?!
