Piwik + drupal: "There is no data for this report." in all reports

I am running piwik 0.9 and want to monitor a drupal site. I’ve installed the piwik module, I can see the javascript snippet in my pages, it seems to be using the right siteid, yet I still don’t see any data in piwik style_emoticons/<#EMO_DIR#>/sad.gif

Thoughts?

Incorrect Piwik tracking code
Seems to be okay, it’s the same as both piwik.org and the piwik dashboard show me

Testing Piwik with disabled Javascript
Not disabled

Do you have logs registered in your Piwik database?
0 rows in the log_visit table.

Using Piwik latest version
Version 1.0 now

All of this done, the problem persists: no error message anywhere, but also no data. Help?

Also, I can see entries in my apache logs:

Getting closer:

I have similar issue (if not the same). I have had Piwik for awhile, and it has been tracking fine, but after manual update couple months ago it has stopped adding any new data. Use latest versions of Piwik, Drupal and Wordpress with respective standard plug-ins.
