Hi! 

I have upgraded a site to version 2.5.0.0. In order to do so I cloned the site (and the DB) and installed all the new files as suggested in the Upgrading instructions . After a little struggling with the connection string. I succeed in upgrading, but I am not able to open the sitesettings page.

Here is the error message:

Any suggestion? 

Thanks in advance
