Fresh Install: Cant access demo course // CSRF token missing or incorrect

I installed a fresh Open Edx install, but when i log in as STAFF im getting this error:

And when i log in as an audit user i get this error:

When i apply the changes recommended here: Ironwood.master course view error

I can see an access my courses BUT the instructor tab always appears even if i log in as and audit, verified or honor learner.

The studio shows correctly the course the clicking on “view as a learner”, but the LMS is not respecting this and its showing the INSTRUCTOR tab for all my learners.

Can you help me please?
