In the comment-info-tip.js.php change

if (!defined(ABSPATH))
{
$directoryPath = dirname(__FILE__).’/';
define(ABSPATH, substr($directoryPath, 0, strpos($directoryPath, ‘/wp-content’) + 1));
}
require_once(ABSPATH . “wp-config.php”);

to

$wp_root = ‘../../..’;
require_once($wp_root.’/wp-config.php’);

In get-comment-info-tip.php change

if (!defined(ABSPATH))
{
$directoryPath = dirname(__FILE__).’/';
define(ABSPATH, substr($directoryPath, 0, strpos($directoryPath, ‘/wp-content’) + 1));
}
include_once(ABSPATH . “wp-config.php”);
include_once(ABSPATH . “wp-includes/rss.php’);

to

$wp_root = ‘../../..’;
include_once($wp_root.’/wp-config.php’);
include_once($wp_root.’/wp-includes/rss.php’);

Now its works fine

Also, very nice plugin, thank you!
