[TYPO3-english] Error after upgrading to 6.1

[Jeppe Donslund]

Hi

After upgrading form 6.0.4 to 6.1 I get this error:


Fatal error: Call to a member function getContentObject() on a 
non-object in 
/var/www/www.domain.com/typo3/sysext/extbase/Classes/Configuration/ConfigurationManager.php 
on line 101

And when I try to edit a page I get an error telling me that username 
and password for the database is not valid

I cannot open Extension Manager either.


Any advice?
