我创建了一个自定义的Wordpress主题，最近媒体库停止了工作。我使用ACF创建自定义字段，当我想选择图像时，媒体库只是不加载而不显示任何图像。
经过一些调试后，我注意到在删除添加自定义窗口小部件的代码时，一切正常。
现在，我的问题是，下面的代码如何影响媒体库的功能？
<!--
This widget is created to display some simple business information like a phone number and an address.
If supplied the widget will also show icons for social medias such as Facebook, Instagram and Twitter.
-->
<?php
class info_widget extends WP_Widget {
function __construct() {
parent::__construct(
// Base ID of your widget
'info_widget',
// Widget name will appear in UI
__('Information Widget', 'wpb_widget_domain'),
// Widget description
array( 'description' => __('Simple widget to display some business information.', 'wpb_widget_domain' ))
);
}
// Creating widget front-end
public function widget($args, $instance) {
// before and after widget arguments are defined by themes
echo $args['before_widget'];
// This is where you run the code and display the output
$phone = __($instance['phone'], 'wpb_widget_domain' );
$address = __($instance['address'], 'wpb_widget_domain' );
$facebook_link = __($instance['facebook_link'], 'wpb_widget_domain' );
$twitter_link = __($instance['twitter_link'], 'wpb_widget_domain' );
$youtube_link = __($instance['youtube_link'], 'wpb_widget_domain' );

我的functions.php文件中加载小部件的代码如下所示：
// Custom info widget
// Register and load the widget
function load_widget() {
register_widget('info_widget');
}
add_action('widgets_init', 'load_widget');
include 'widgets/information_widget.php';
非常感谢任何帮助，而且我对Wordpress相对较新，所以我可能错过了一些明显的东西，但媒体库停止工作似乎很奇怪。 还应该注意的是，小部件本身正常工作，包括后端和前端！
