I updated to 0.4 and now I find quite a lot of these errors in error_log:
PHP Fatal error: Class 'Zend_Registry' not found in XXXXX/piwik/core/Common.php on line 112
I am aware of the older threads and bugreports, but the solutions didn’t work for me.
- double check, that all files are at place
- check writing permissions on tmp and config
- delete cache and cookies
I do not see any fault in the UI, only in the logfile.
