Coursepress is working, but after clicking "Sign out" and "Profile" I get 404 er

I have installed Coursepress pro and it works. I configured the menu items to redirect to pages with the captions like [cp_pages page="student_dashboard"], etc. and it works, but when I am logged in and I close my account by clicking "sign out" I get a 404 not found. Also, when I go to "Profile" it redirects to the right page, but inside the page I get "not found" where the caption is placed.
