Warning: Undefined array key „00“

Hallo zusammen, nachdem ich eine Website auf php 8 geupdated habe, erhalte ich auf einer Seite, in der Programmlogik implementiert ist, die oben genannte Fehlermeldung.

Warning: Undefined array key „00“ in „[…]/class-wp-locale.php“

Ich habe mir die Datei „class-wp-locale“ angeschaut und der Abschnitt in der Datei beinhaltet die folgende Funktion:

/*** Retrieves the full translated month by month number.** The $month_number parameter has to be a string* because it must have the '0' in front of any number* that is less than 10. Starts from '01' and ends at* '12'.** You can use an integer instead and it will add the* '0' before the numbers less than 10 for you.** @since 2.1.0** @param string|int $month_number '01' through '12'.* @return string Translated full month name.*/public function get_month( $month_number ) {    return $this->month[ zeroise( $month_number, 2 ) ];}

Ich verstehe ehrlich gesagt nicht, wie der Wert „00“ zustande kommt und auch nicht der Code von einem Plugin darein geschrieben wurde oder ob das zu WordPress gehört.

Testweise habe ich alle Plugins deaktiviert. Der Fehler existiert dann jedoch immer noch.
Über einen Hinweis würde ich mich freuen.

Anbei noch der Bericht über den Website Zustand:
