Error on main plugin page

I’m getting an error on the main plugin page directly after installation. Clicking on ‘Cunjo’ in the left hand side of the WordPress dashboard leads to a blank page. Scrolling down that page, I see a youtube video. Resting on top of that youtube video is this error message:

Notice: Undefined index: stream_message in /path/to/the/plugin/wp-content/plugins/share-social/views/general/introduction.php on line 4

(Note: my path has been obscured, it does not actually say /path/to/the/plugin/)

I’m not sure if the page is supposed to be blank or not as I’ve just installed the plugin for the first time.
