Problem with changing ticket status

Hallo everyone!

I upgraded RT to 2-0-15 (from 2-0-14)
I did
make upgrade

rt works, but is not possible to change ticket status. (and queue name, times)

access to database is possible (i can change ticket status by update Tickets
set Status=“resolved” where Id=xxx from commandline as rt database user)

Can someone tell me whats wrong ?
