Got this error when using 'Intense Shortcode' for their FAQ.

Fatal error: Call to a member function is_main_query() on a non-object in /home/otte/public_html/otte2014/wp-content/plugins/events-and-bookings/lib/default_filters.php on line 122

I have only have Event+ plugin install so i assume this error is pointing to the folder of it.

Need some advise and direction.
