The original events archive link doesnt work + the upcoming events is not showing

I have the events+ plugin on the site. The event archive page is not showing the list of events and the widget for upcoming events also doesn’t show up (currently enabled).

Is there any shortcode for the events archive page? so that I can use the sortcode in a page for showing the list of events?

links: (the main events link) (link for a category of events – shows)
