使用wordpress主题子项的load_theme_textdomain无法与我一起使用

我有一个问题, 我想使用子主题加载textdomain。子主题中的功能页面仅包含以下代码。

<?php
add_action( 'after_setup_theme', 'poseidon_child_setup');
function poseidon_child_setup() {

// Poseidon theme for translation
load_child_theme_textdomain( 'poseidon-child', get_stylesheet_directory() . '/languages' );
}

这是父function.php的代码的一部分

if (!function_exists('poseidon_setup')) :

/**
 * Sets up theme defaults and registers support for various WordPress features.
 *
 * Note that this function is hooked into the after_setup_theme hook, which
 * runs before the init hook. The init hook is too late for some features, such
 * as indicating support for post thumbnails.
 */
function poseidon_setup() {

    // Make theme available for translation. Translations can be filed in the /languages/ directory.
    load_theme_textdomain('poseidon', get_template_directory() . '/languages');

    // Add default posts and comments RSS feed links to head.
    add_theme_support('automatic-feed-links');

    // Let WordPress manage the document title.
    add_theme_support('title-tag');

    // Enable support for Post Thumbnails on posts and pages.
    add_theme_support('post-thumbnails');

    // Set detfault Post Thumbnail size.
    set_post_thumbnail_size(840, 560, true);

    // Register Navigation Menu.
    register_nav_menu('primary', esc_html__('Main Navigation', 'poseidon'));

    // Switch default core markup for search form, comment form, and comments to output valid HTML5.
    add_theme_support('html5', array(
        'comment-form', 'comment-list', 'gallery', 'caption', ));

    // Set up the WordPress core custom background feature.
    add_theme_support('custom-background', apply_filters('poseidon_custom_background_args', array('default-color' => 'ffffff')));

    // Set up the WordPress core custom logo feature.
    add_theme_support('custom-logo', apply_filters('poseidon_custom_logo_args', array(
        'height' => 50, 'width' => 250, 'flex-height' => true, 'flex-width' => true, )));

    // Set up the WordPress core custom header feature.
    add_theme_support('custom-header', apply_filters('poseidon_custom_header_args', array(
        'header-text' => false, 'width' => 2500, 'height' => 625, 'flex-height' => true, )));

    // Add Theme Support for wooCommerce.
    add_theme_support('woocommerce');

    // Add extra theme styling to the visual editor.
    add_editor_style(array('css/editor-style.css', poseidon_google_fonts_url()));

    // Add Theme Support for Selective Refresh in Customizer.
    add_theme_support('customize-selective-refresh-widgets');
}
endif;
add_action('after_setup_theme', 'poseidon_setup');

我希望能帮助我解决此问题, 并尝试挂钩其他一些函数, 但似乎也无法正常工作, 但是当我使用}或)或;时；在子function.php中, 我得到一个错误, 这意味着子文件可执行文件中的function.php, 但是我不知道为什么其中没有任何作用。

子主题中的languages文件夹包含以下文件：

poseidon.pot
ar.po
ar.mo

#1

你必须改用父母的文本域：

// Poseidon theme for translation
load_child_theme_textdomain( 'poseidon', get_stylesheet_directory() . '/languages' );
