While trying to perform the one-click update to 1.8.3, I got this error message:
Fatal error: Undefined class constant ‘Piwik_ReportRenderer::HTML_FORMAT’ in [PATH_TO_PIWIK]/core/PluginsManager.php on line 427
([PATH_TO_PIWIK] being the path to Piwik on my server)
This messed up the whole installation, and I was unable to access Piwik at all. I had to delete and reinstall it. The subsequent database update seems to have worked fine.
Tracking works again, but I can’t view some of the reports, now getting the following error message:
Notice: Undefined index: enable_auto_database_size_estimate in [PATH_TO_PIWIK]/plugins/PrivacyManager/PrivacyManager.php on line 131

Hope this helps debugging. Any quick remedy for me?
Many thanks!
EDIT: OK, figured it out. Disabling the PrivacyManager plugin seems to help… Which of course means that I can’t use it.
