Creates errors on Category Pages

Thanks for this plugin! It fills a real need. I am having issues on standard category theme templates

`Warning: Invalid argument supplied for foreach() in /home/haumcdi4/public_html/wp-content/plugins/gravity-forms-custom-post-types/gfcptaddonbase.php on line 116

This error is thrown twice on a category page with no forms. Please help!
