When I use this code (specifying an entire year of past and upcoming events), Calendar only displays upcoming events and fails to display events which have already passed.
{exp:calendar:events date_range_start="2013-08-01" date_range_end="2014-08-01"}
(The behavior is the same when I use the {exp:calendar:cal}
tag pair.)
How can I get past events to show up in my event list?
