Listing a couple of events using:
em_events( array('limit'=>1,'orderby'=>'event_start_date') ); works fine.
As soon as I add
'array'=>true to the arguments to get the output as an array I get the following error:
Fatal error: Call to a member function output() on a non-object in [..]/wp-content/plugins/events-manager/classes/em-events.php on line 199
I think this is a bug?
