更新：找到问题的原因。主题是这样的
add_action(\'init\',\'ezgz_buffer\');
function ezgz_buffer()
{
ob_start(\'ob_gzhandler\');
}
如果访问者的浏览器能够处理gzip压缩，则上述代码将启用gzip压缩。
实际问题：
这对我来说真的很奇怪，我花了几个小时才弄明白。
W3 Total Cache插件已安装并处于活动状态。预览模式已禁用。页面缓存、缩小和对象缓存已启用。为页面缓存、缩小、对象缓存启用了“Degg模式”。
现在，我希望W3 Total cache能够工作并在html页面中显示调试日志，但它没有：(
站点正在加载，就像W3TC不存在一样。
检查：
- 。htaccess文件中包含了W3总缓存所需的所有规则。（漂亮的permalinks正在发挥作用。）
- wp配置。php文件具有
define(\'WP_CACHE\', true);服务器模块（&M）；资源：

多次单击“emtpy all caches”（即使它似乎不起作用）。不知道怎么回事。我昨晚开始的，我甚至认为是因为我困了。所以好好睡了一觉，还是一样，不只是一场梦。

因为这些模块都没有安装在服务器中，所以W3 Total Cache做不了什么。因此，基本上，（磁盘）增强模式下的“页面缓存”无法工作。您可以在中尝试“页面缓存”
Disk: basic 模式
不过，我不知道为什么“对象缓存”和“缩小”不起作用。
