Undefined property Error

Hi,

I have a little problem, and i don’t know what it is.
——
Site Information:
Theme Blanco
Plugin Woocommerce
Plugin WPML
——
Error 1:
Notice: Undefined property: stdClass::$term_id in /home/vhosting/h/vhost0056005/domains/unlimitedtowels.com/htdocs/www/wp-content/themes/blanco/woocommerce/archive-product.php on line 27

Error 2:
Notice: Undefined property: stdClass::$term_id in /home/vhosting/h/vhost0056005/domains/unlimitedtowels.com/htdocs/www/wp-content/themes/blanco/code/woo.php on line 284

You can see the error here: http://www.unlimitedtowels.com/en/shop/

Has someone any idea in which direction I should look to fix this?

Thanks in advance

Job.
