I am also having the same/similar issue. I get it when I attempt to install the plugin. Could there be a conflict with some other plugins?
https://www.amplifiedradio.com and i get this error: Fatal error: Class ‘Phar’ not found in /home/thecider/public_html/amplifiedradiotest.com/blog/wp-content/plugins/hearthisat/httpful.phar on line 3
(Yes it is a subdomain account, with a strange re-direct)
But if your getting the same error above….
