Event pages not found?

Is it normal that, after installing the plugin, that all the event summary pages like Event list, categories, location, etc. created are missing when the browser tries to get there (404)? Do I need to do something before seeing them? The individual event pages show up fine if I access their URL directly.

I am using a new and clean WP install, with no other plugins and the Twenty Sixteen/ Twenty Twelve themes.

Thanks!
