[Koha] Koha Staff login: Error: You do not have permission to access this page

We have moved from Koha 3.0.6 to 3.4.5 and we are facing the following problem: Login to the staff interface (:8080) gives the following error: (except for kohaadmin which is fine) Error: You do not have permission to access this page The user HAS superlibrarian Access to all librarian functions set. Login with the same user on :80 is fine. When we create a new user with superlibrarian access the login is ok. Is there anything we need to do to enable staff access?
