Hi Guys,
I experienced this as well that is because our server is currently running a php version 5.3 and array dereferencing is not supported. As per error message it says an error on line 139 and the code is $shares_counts = $wpdb->get_results($query, ARRAY_N)[0][0];
so what i did to resolve the issue is to change line 139 to this $shares_counts = $wpdb->get_results($query, ARRAY_N); and on line 141 return $shares_counts[0][0] save the file and upload it again you can now activate the plugin.
Hope that helps
