Installation without any problems - no configuration possible (no replies)

Hi there,

i installed actual piwik flawless on my webserver. But, in backend there are some strange problems:

1. If i try to set some configurations, they aren't saved and i get an error "token is wrong"
2. I do not see the Javascript Code (empty box)
3. In the tracking tab i can't set any radio buttons (seems they are disabled)

Does any one know about that strange behaviour?

Best regards
