Immer die Warnung: Argument 2 für manage_posts_custom_column () fehlt?

Ich habe einen benutzerdefinierten Beitragstyp und zwei benutzerdefinierte Taxonomien erstellt und diese im Abschnitt "Beitrag verwalten" angezeigt. Es wird jedoch die folgende Warnung angezeigt:

Welches Argument fehlt mir?

Ändern Sie die Zeile 93 von

add_filter('manage_posts_custom_column', 'manage_posts_custom_column');

zu

add_filter('manage_posts_custom_column', 'manage_posts_custom_column', 10, 2);

Das vierte Argument gibt an, wie viele Argumente die Funktion manage_posts_custom_column akzeptiert (standardmäßig eines).

Codex: add_filter()
