piwik 2.0 had no data in all reports (2 replies)

hi all,

I've just install piwik 2.0, its the first time i using piwik, after install, i insert tracking code into my website ( into head tag ).

<!-- Piwik -->
<script type="text/javascript">
  var _paq = _paq || [];
  _paq.push(["trackPageView"]);
  _paq.push(["enableLinkTracking"]);

  (function() {
    var u=(("https:" == document.location.protocol) ? "https" : "http") + "://<my piwik address>/";
    _paq.push(["setTrackerUrl", u+"piwik.php"]);
    _paq.push(["setSiteId", "1"]);
    var d=document, g=d.createElement("script"), s=d.getElementsByTagName("script")[0]; g.type="text/javascript";
    g.defer=true; g.async=true; g.src=u+"piwik.js"; s.parentNode.insertBefore(g,s);
  })();
</script>
<!-- End Piwik Code -->
