经过多年的良好运行，我在更新到5.42后突然收到了这个可怕的消息。但是，它只在管理员中发生：

Warning: strpos() expects parameter 1 to be string, array given in Warning/home/content/55/html/example/wp-includes/media.php on line 3141

介质第3140行的代码。php是

if（\'attachment\'===$对象\\u类型| | 0===strpos（$object\\u类型，\'attachment:\'））{

问题似乎是我的自定义分类法。这是在functions（）中创建的。php

function songs_init() {
    // create a new taxonomy
register_taxonomy(
        \'songs\',
        array(
            \'label\' => __( \'Songs_Tax\' ),
            \'sort\' => true,
            \'args\' => array( \'orderby\' => \'term_order\' ),
)
);
}
add_action( \'init\', \'songs_init\' );

当我在媒体中测试有问题的$object\\u类型时。pho并获取var\\u dump（），返回$object\\u type是一个数组：

\'orderby\' => \'term_order\'

我试着在函数中寻找空白和离群字符。php，但我什么都没看到。

下一步该怎么做？同样，在5.42之前的近十年中，这项技术一直运行良好

    register_taxonomy(
        \'songs_tax\',
        \'songs\',
        array(
            \'label\' => __( \'Songs_Tax\' ),
            \'sort\' => true,
            \'args\' => array( \'orderby\' => \'term_order\' ),
        )
    );
