You can control online registration from the "Promote" page, accessible from the header menu.
Under both the "Student Registration" and "Volunteer Registration" headings on that page, there is a toggle switch to enable or disable registration. Changes made to those switches take effect immediately.
Please Note: For people to be able to register online, 1) registration must be enabled, and 2) the public page must be published.
