First, let me state I absolutely love this plugin. However, I'm having a real serious issue that I can't seem to resolve.
It appears that since the WordPress 3.3 update my front end calendar does not display to users who are not logged in.
When I'm logged into WP-Admin I can see the calendar in both admin and on the public site just fine. But when logged out (regardless of browser) it does not work.
The calendar url is http://www.yourquadcities.com/quad-cities-events-calendar/
