Look at both path and domain parameters for the setcookie function. Reference: setcookie @ PHP docs http://php.net/manual/en/function.setcookie.php

Try this to set your cookie:

if ($on_localhost) { // change this
    $domain = '.localhost';
} else {
    $domain = '.webhoster.com'; // change this
}
setcookie(
    'settings',
    serialize($defaultSettings),
    time()+3600*24*30,
    '/',          // this is the path
    $domain       // this is the domain
);

Good luck!
