No data from mediawiki

I can’t get Piwik to record data from my mediawiki wiki.
The wiki is at Free Hosting - Domain Does Not Exist
i.e. it is in a folder.

Piwik is installed in a folder off this.
i.e. mw/extensions/piwik

The lines I have added to LocalSettings.php are:
require_once “$IP/extensions/piwik/piwik.php”;
$wgPiwikURL = “Free Hosting - Domain Does Not Exist”;
$wgPiwikIDSite = “1”;

I have assumed that I would see some data after about an hour, but I can’t.
Can anyone point out what I have done wrong?
