Hi everyone.
I am getting this error very ofter.
Error in Piwik (tracker): Invalid idSite: '0', referer: http://www.example.com/my-page.html
I have site with about 100.000 pageviews per week and this error happens ones every 10-15 second in the apache log.
It definitely comes from core/Tracker/Request.php
core/Tracker/Request.php
Is there any solution for this? I believe its a bug because I have only 1 site with PIWIK tracking code installed and about half of traffic actually makes on the PIWIK end.
