Visitors by server time is empty after upgrade

I upgraded to 0.2.29 and now “Visitors by server time” is empty.
I also did a clean install and just copied the config file but with the same result.

Anyone, what might be wrong?

Can you check your server error logs and browser’s error console?

Hup, now it works. Hmmm… strange.

Don’t know if I’m able to access the error log from my ISP.
I’ll post it here if I’m able to retreve it.
