could you help me? After a few clicks through piwik i get this Fatal error: Function __autoload(PMA_Theme_Manager) threw an exception of type ‘Exception’ in /xyz/piwik/libs/Zend/Session.php on line 395. When I restart my Browser (IE 7.0.) piwik works again, for a few clicks. Could you tell what I can change to handle this error. Thank you very much for your help.
