Not able to have events show up...error page displays call stack

I installed JEvents and set up everything correctly but I am unable to view any events. I created a menu item to show a calendar page but I get an error page when I click on the menu item. I also installed the calendar module on my home page and it shows up when when you click on an event date it also goes to an error page. I don't know what to do...please help (BTW my events are in November & December 2017).

On the error page is the following:

Invalid controller: name='', format=''
