Upfront is not loading some widgets

Hello,

Im using some woocommerce widgets in this site but some of them are not working.

Turned on WP debug and I saw this messages:

Notice: Undefined index: widget_id in /home/jpjuliao/public_html/neucaribe.oneclick.com.co/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-widget.php on line 79

Notice: Undefined index: widget_id in /home/jpjuliao/public_html/neucaribe.oneclick.com.co/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-widget.php on line 95

Along with "Ooops, something seems to have gone wrong with rendering the widget".

The widgets that are not working are woocommerce layered nav and woocommerce layered nav filters.

Any ideas?
