we tried to upgrade to piwik 1.12 to 2.0.3 and we have a strange behavoir.
Database upgrade went fine, but the piwik dashboard does not work.
Everything is rendered fine, but no statistics and I cannot change the website with the pull-down menu (please see the attached screenshot).
Browser cache was deleted, I also deleted the piwik folder and re-uploaded the files. Same result.
So far there are also no errors in the apache log. Running with
PHP 5.3.18 (cli) (built: Nov 18 2012 10:15:33)

The internal check of Piwik is running fine: Huzzah! There are no problems with your Piwik setup. Give yourself a pat on the back.
Thanks for any advice,
