Woocomerce Fehlermeldung: Internal Server Error

Wenn ich in meinem Onlineshop eine Test Bestellung mache bekomme ich nachdem ich meine Kontakt Daten eingegeben habe und zu den Bezahloptionen weiter gehen möchte folgende Fehlermeldung: Internal Server Error

In den Server Logs werden die Folgenden fehler angezeigt:

AH01071: Got error 'PHP message: The WC_Cart::get_item_data function is deprecated since version 3.3. Replace with wc_get_formatted_cart_item_data.\nPHP message: The WC_Cart::get_remove_url function is deprecated since version 3.3. Replace with wc_get_cart_remove_url.\n', referer: https://golfklub-braunschweig.de/produkt/golfball-nxt-tour/

und dieser hier:

Ich werde nicht schlau daraus. Wie kann ich das lösen.
Kann es daran liegen das ich die Domain vor kurzem umgezogen habe?
Kann es daran liegen das ich vor kurzem ein Woocomerce Uptdate gemacht habe und dies nun nicht mehr mit dem Plugin der Bezahlschnittstelle (Crefopay) kompatibel ist.

Kann jemand diese Fahlermeldung für mich so breschreiben das ich sie auch verstehe.

bitte um schnelle hilfe, danke im Vorraus.
