I installed the plugin and created some events.
I used the list events widget in one of the sidebars, and the events I created are showing up correctly on the page
But when I click the "show all events" link to go to
I get a "page not found" error.
In the same way
shows either the "Event List" or "Calendar" view just fine, but clicking any of the links from that point generate a "page not found".
