To access the menu in Student View, try clicking on the "hamburger" menu (three horizontal lines) next to the course name at the top. From your screenshot it appears that the menu is closed; clicking on the hamburger should open it.
Regarding the grading quarters, you probably need to consult with your institution's Canvas admin. Grading Periods are set by the institution, not by Instructure/Canvas. I would guess that your institution set a "close" date that has already passed. (The Close Date is different from the End Date for the Grading Period. The Close Date is the last day instructors can access the course material.)
