Reply To: Error after updating

I did it, but still error. To be precise:
few hours ago i had 2.9 and i updated wp and theme to 2.10 and i got the same message. I got the same message in backend “header builder” also. So i decided to reinstall a fresh wp + theme and downloaded the latest one 30mins ago. But like you can see on my page the error persists.
I reinstalled by erasing the folder of /www so nothing could go in conflict
