Wordpress 自定义主题在页面重新加载时有 mod-pagespeed 没有延迟 404 错误

Question

问题： 在重新加载 Wordpress 4.1 自定义主题的页面时，我在控制台中收到错误 "GET ... /%3Cscript%20pagespeed_no_defer= 404 (Not Found)"，并且在网页上显示脚本。如果我再刷新几次，它就会消失，然后再刷新一次，它就会 returns.

目标/问题： 关于如何进一步解决此错误的指导？这就像仅禁用此功能一样简单吗？最重要的是，我想了解为什么会出现此问题。感谢您的宝贵时间！

解决方法： 如果我在 httpd.conf 中禁用 pagespeed，问题就会消失。

环境： 客户端：OS X 10.10.2，Chrome 40.0.2214.94（64 位），Safari 8.0.3，FF 35.0 .1;服务器：Bitnami VM，Ubuntu 14.04，Wordpress 4.1

背景： 我正在创建一个基本的 Wordpress 主题。我从 underscores.me/ 中的模板开始，并添加了一些通用的 .js（bootstrap，等等...）当我第一次加载页面时，它看起来不错。当我点击刷新时，它把 js 代码扔进了正文。我是使用 PageSpeed 的新手，所以任何指导将不胜感激。我开发了其他主题和插件，但这对我来说是个新问题。

https://developers.google.com/speed/pagespeed/service/DeferJavaScript 如果答案在这里，我没看到...

我还有更多链接，但这些是最相关的。

这是页面正确加载时的示例...
