获取以下错误：
警告：date（）要求参数2较长，中给出的字符串/home/users/2/catfood.jp-cebcat/web/academy/wp-includes/functions.php在线112
哪条线指向：
$datemonth = $wp_locale->get_month( $datefunc( 'm', $i ) );
需要对上述行进行哪些更改才能解决此问题？
这是的全部代码

global $wp_locale;
$i = $unixtimestamp;
if ( false === $i ) {
if ( ! $gmt )
$i = current_time( 'timestamp' );
else
$i = time();
// we should not let date() interfere with our
// specially computed timestamp
$gmt = true;
}

$datefunc显然是php的日期方法的别名。如果是这种情况，那么您正试图通过传递单个整数1-12来获取月份。如果不能做到这一点，则需要将时间戳传递给PHP的日期方法，然后根据作为选项传递的属性，返回以下数据。然后将其传递给wordpress locale get_month方法，该方法返回月份的名称。您需要重构代码，这样$i就不是for循环变量。如果你只是想让一月-十二月只做
$i = 1;
$monthArray = [];
do {
// Just push the months to an array and pass it to the view
array_push($monthArray, $wp_locale->get_month($i);
$i++;
} while($i < 13);
然后用它做你需要做的事情。如果你要从数据库中取回一条记录，你需要在返回的模型中访问适当的值。否则，您将传递一个数组对象。如果你正在访问一个你应该做的模型）
// Access the property that you intended to retrieve the month on.
$datemonth = $wp_locale->get_month( $datefunc( 'm', $i['published_at'] ) );
我添加了一个名为"付费会员专业版"的插件，这个插件是用英语写的，我把它翻译成了日语。有很多这样的代码：
<?php printf(__('課金 #%s ( %s )', 'pmpro'), $pmpro_invoice->code, date_i18n(get_option('date_format'), $pmpro_invoice->timestamp));?>
我尝试更改这些代码如下：
时间戳），$pmpro_invoice->code）；？>我想这就是它造成问题的原因。你觉得怎么样？
现在我再次下载了插件，没有任何问题。
谢谢你帮我。
