Update generates errors after adding to cart

Hey Guys,

I just performed an update of woocommerce. Our website is usually up-to-date but this one was waiting.

I just tried adding a product to a vcart and this is the error i get:

Warning: A non-numeric value encountered in /customers/6/7/1/etserv.be/httpd.www/wp-content/plugins/woocommerce/includes/class-wc-cart-totals.php on line 234 Warning: A non-numeric value encountered in /customers/6/7/1/etserv.be/httpd.www/wp-content/plugins/woocommerce/includes/class-wc-discounts.php on line 88 Warning: Cannot modify header information – headers already sent by (output started at /customers/6/7/1/etserv.be/httpd.www/wp-content/plugins/woocommerce/includes/class-wc-cart-totals.php:234) in /customers/6/7/1/etserv.be/httpd.www/wp-includes/pluggable.php on line 1216

Any idea where this is coming from?

Thanks

Roger
