I absolutely love Piwik. It is soooo useful for my small website.
Yesterday I tried to update to 2.1.0 but recived the following error messages, and I cannot find any way to get Piwik back on my website??
Fatal error: Undefined class constant ‘Piwik\ReportRenderer::CSV_FORMAT’ in /home/a2515/public_html/piwidir/core/Plugin/Manager.php on line 736
Fatal error: Call to undefined method Piwik\Piwik::hasUserSuperUserAccess() in /home/a2515/public_html/piwidir/plugins/CorePluginsAdmin/Controller.php on line 364
I have also deleted config/config.ini.php as recommended in the Help section.
Please would you advise an Idiots guide to how I can get Piwik back asap.
Thank you so much.
