Hi wolte auf die 2.0 Beta updaten leider klappt das nicht ich werde aus der Fehlermeldung auch nicht wirklich schlau.

That hints to a/your templates config.inc.php file including a navigation configuration. (*)
Did you take the official beta zip from http://www.s9y.org/12.html ?
It might be better to take this pre beta3 zip https://github.com/s9y/Serendipity/archive/2.0.zip, since we have changed and fixed a lot concerning templating fallback mode and config checks.
Or downgrade to 1.7.8 and wait for the official beta3 or even the RC phase.

(*) I remember long time ago having had something similar, which was based to a wrong index key, which assigning the wrong NAV_DEFAULT_n constant smarty var.
