Visitors unable to see the Events

Hi,

I have created 2 events, https://healthradii.com/events/ only if I loginin from the backend(wp-admin) I am able to see the events, but if I logout(Visitor) I am unable to see the events I get the error something like this
“Error 404 – Page not found!
The page you are trying to reach does not exist, or has been moved. Please use the menus or the search box to find what you are looking for.
“
I am unable to figure out where I am going wrong.

Thanks for help.
Harsha.
