After 0.2.32 Update

Hello all,
After i updated my Piwik, i’ve one error :
No entry is registered for key 'config’

#0 /home/http/stats/core/FrontController.php(228): Zend_Registry::get(‘config’)
#1 /home/http/stats/index.php(50): Piwik_FrontController->init()
#2 {main}

Somebody can help me ?

try to reupload all files from the latest piwik version; it may be that some files failed uploading?

if not, backup config/config.ini.php, then delete it, then go to piwik, it will reinstall it (select “keep my existing tables”); does it fix it?
