Weekly Event Calendar - FATAL ERROR

Hello,
http://totalevolutionwarren.com/class-schedule/
I am attempting to display the weekly calendar. I used the shortcode: [weekly_event_calendar]

But I am getting this error:
Fatal error: Call to a member function get_option() on array in /home/icyyink/public_html/wp-content/plugins/events-and-bookings/lib/plugins/eab-events_weekly_calendar.php on line 216

Can anyone help??
