调用未定义函数upload_is_user_over_quota()

Question

我有两个不同的多站点：

• www.example.org
• www.example-two.org

在这两个站点上，都有5个子站点。

它们托管在同一台服务器上(我已经使用VirtualMin安装了该服务器)。所有10个子网站都有相同的父主题，不同的子主题也有细微的变化。

我已经把网站转换成古腾堡了，但是每当我上传一张图片，我就会得到这样的错误：

The response is not a valid JSON response.

..。在这里看到：

在错误日志中，我得到了以下错误：

看起来其他 是 体验这个错误也是如此。

有人知道解决办法或解决办法吗？

Answer 1

在挖掘过程中，这似乎是一个bug，在4.9.8中添加了WordPress。这个补丁似乎在Multisite上通过REST上传了中断的附件，因为它使用了一个来自未加载REST请求的文件中的函数。

我已经报告了窃听器这里。

一个快速而肮脏的解决方法是将其添加到主题的functions.php文件中，或者是一个简单的插件：

if ( ! function_exists( 'upload_is_user_over_quota' ) ) {
    function upload_is_user_over_quota( $echo ) {
        return false;
    }
}

这个函数不会做它应该做的事情，但是它将防止致命的错误发生。
