I have the same problem as the original poster. Only direct entries shown in the reports, but in my case there is a &urlref= parameter in the logs.Other things suich as browser, screen resolution etc. are recorded, but no referrer and then of course no search engine keywords. Another thing that is missing are the pages in the Actions/Pages report. only “Page URL not defined”. I do get the page title report, however.
This is a log entry (my domain replaced by example.com)

I use Piwik 1.8.2. The site is a Drupal site, with the Piwik code inserted in the template (not using the Piwik module).
Thanks for any advise.
