Wordpress：“警告：非法字符串偏移”在多个地方

Question

希望你们能在这里帮助我。在我的 WordPress 安装中这些问题发生了什么，请参阅错误和引用的代码块。

错误：

Warning: Illegal string offset 'domain' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 583

Warning: Illegal string offset 'context' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 587

Warning: Illegal string offset 'singular' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 588

Warning: Illegal string offset 'plural' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 588

Warning: Illegal string offset 'context' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 588

Warning: Illegal string offset 'domain' in /home/customer/www/xxxxxxxx.xxx/public_html/wp-includes/l10n.php on line 583

代码：

function translate_nooped_plural( $nooped_plural, $count, $domain = 'default' ) {

    if ( $nooped_plural['domain'] ) {

        $domain = $nooped_plural['domain'];

    }

    if ( $nooped_plural['context'] ) {

        return _nx( $nooped_plural['singular'], $nooped_plural['plural'], $count, $nooped_plural['context'], $domain );

    } else {

        return _n( $nooped_plural['singular'], $nooped_plural['plural'], $count, $domain );

    }

}

Warning: Illegal string offset 'something'消息意味着您正在尝试访问的值，$someVar['something']但它不存在。为避免这种情况，您应该始终使用isset($someVar['something'])检查给定变量中是否存在（或不存在）索引。
