Wordpress admin-ajax.php 返回 php 代码而不是 json

Question

如何让 WordPress 在 Nginx 上返回 JSON？

在我的 wordpress 中，Ajax 调用返回 <?php JSON 而只是简单的 JSON。 该站点运行良好，除了 admin-ajax 调用。

定期通话

文件上传调用

技术信息：

Wordpress 4.5
PHP 5.6.11-1ubuntu3.1 (fpm-fcgi)
nginx version: nginx/1.9.3 (Ubuntu)

只是为了结束这个话题。 问题是functions.php文件中没有评论 我在functions.php添加以下内容后，问题就消失了。

<?php
/**
 * Twenty Fifteen functions and definitions
 *
 * Set up the theme and provides some helper functions, which are used in the
 * theme as custom template tags. Others are attached to action and filter
 * hooks in WordPress to change core functionality.
 *
 * When using a child theme you can override certain functions (those wrapped
 * in a function_exists() call) by defining them first in your child theme's
 * functions.php file. The child theme's functions.php file is included before
 * the parent theme's file, so the child theme functions would be used.
 *
 * @link https://codex.wordpress.org/Theme_Development
 * @link https://codex.wordpress.org/Child_Themes
 *
 * Functions that are not pluggable (not wrapped in function_exists()) are
 * instead attached to a filter or action hook.
 *
 * For more information on hooks, actions, and filters,

 *
 * @package WordPress
 * @subpackage Twenty_Fifteen
 * @since Twenty Fifteen 1.0

检查您的 wordpress 文件是否未被泄露。您可能在核心 Wordpress 文件中进行了一些修改，添加了“

重新安装 Wordpress 文件并检查它是否仍然存在。 对 wordpress 的所有修改都应该在主题文件夹或插件中完成。

我的问题仍然存在尝试禁用所有插件并一一打开。有可能是其中一个插件搞砸了。
