Cannot use a scalar value as an array

These lines (38, 39, 40) are throwing an error (“Cannot use a scalar value as an array”):

if(empty($instance['adid'])) $instance['adid'] = 0;
if(empty($instance['siteid'])) $instance['siteid'] = $blog_id;
if(empty($instance['title'])) $instance['title'] = '';

It’s in adrotate-widget.php

EDIT:
When i tried to declare $instace as an array like so: $instance = array();
…i got empty ads. No errors, but no ads too.
