Chyba v košíku

Zdravím, sťahoval som svoj web z jedného hostingu na druhý. Po presťahovaní mám problém, v košíku mi vyskakujú chyby:

Warning: Declaration of WC_Shipping_Ceske_Sluzby_Ulozenka::calculate_shipping($package) should be compatible with WC_Shipping_Method::calculate_shipping($package = Array) in /web/htdocs3/doposk/home/www/wp-content/plugins/ceske-sluzby/includes/class-ceske-sluzby-ulozenka.php on line 0

Warning: Declaration of WC_Shipping_Ceske_Sluzby_DPD_ParcelShop::calculate_shipping($package) should be compatible with WC_Shipping_Method::calculate_shipping($package = Array) in /web/htdocs3/doposk/home/www/wp-content/plugins/ceske-sluzby/includes/class-ceske-sluzby-dpd-parcelshop.php on line 0

Viete mi s tým pomôcť?
