Achievment Shortcode error

Hey all!

I just installed Gamipress and I am excited to see what all I can add to my site with it! I did have an error, when I used the achievement shortcode to list all achievements on a page, it gave the following error:

Warning: Illegal offset type in isset or empty in /home/sagaborn/public_html/darkreturn.com/wp-content/plugins/gamipress/includes/achievement-functions.php on line 331

Shortcode used:
[gamipress_achievements type=”badge” columns=”1″ filter=”no” filter_value=”all” search=”yes” load_more=”yes” limit=”10″ orderby=”menu_order” order=”ASC” current_user=”no” title=”yes” link=”yes” thumbnail=”yes” excerpt=”yes” steps=”yes” toggle=”yes” earners=”no” layout=”left”]

Thanks for any help!
