php - WooCommerce - empty cart when proceed to checkout -

i updated woocommerce newest version (2.2.6) , have issue.

when client isn't logged - after proceeding checkout gets cart page empty cart.

i var_dump'ed $_session , woocommerce's cart before checkout , should there - was:

global $woocommerce; var_dump($_session); var_dump($woocommerce->cart->get_cart());

note: on localhost works fine, when i'm logged or not. on domain - above.
