Undefined index: onlycategory

Installed the plugin and placed the following in one of my theme files:

<?php echo do_shortcode('[jQueryArchiveList onlycategory="1" showcount="1" showpost="1"]'); ?>

Resulted in the following error messages being displayed prior to showing the archive list:

Notice: Undefined index: onlycategory in /var/www/gcihs/wp-content/plugins/jquery-archive-list-widget/jquery-archive-list-widget.php on line 311

TEMP SOLUTION – ADDED ,'onlycategory' => 0 to the defaults array
