I just installed Piwik on one of my sites, and it works for the most part. But erratically, usually (but not always) when I reload a page or go somewhere other than the dashboard, the application completely bugs out and throws this error:
Fatal error: Function __autoload(user) threw an exception of type ‘Exception’ in /www/my_awesome_website/web/content/piwik/libs/Zend/Session.php on line 395
The only way to get it to work again after this is to clear my session (close the browser). It’s to the point where it’s difficult to do anything except view the Piwik dashboard, and even then I’m not certain the statistics are generating properly.
BTW this is hosted on Mosso’s Rackspace Cloud if that makes any difference.
