看起来是：

当访问：

www.crifan.com/index.php

时，出错的地方，中间都是

plugins/accelerated-mobile-pages

导致的。

-》所以先去研究看看啥原因，

不行的话，就去禁止AMP插件

wordpress extract by downloading image() unknown:0

wp-content/plugins/accelerated-mobile-pages/includes/vendor

php slow wp-content/plugins/accelerated-mobile-pages/includes/vendor

Mendadak Bisa Masak dengan SHARP Healsio Automatic Cookware | My Foottrip

Fatal PHP error caused by is_amp_endpoint() · Issue #608 · Automattic/amp-wp

php slow script_filename index.php fopen

amp_render() unknown:0

lnmp wordpress amp_render

Topic: AMP & Php7 error 500 « WordPress.org Forums

人家是安装了php7.0-xml

就可以了。

算了。我还是先去禁止掉amp吧。

【总结】

没去没有完全搞懂，slow的log中反映出来的慢，具体是哪些步骤执行的慢，但是可以看出来是：

AMP插件的问题

所以暂时就先去停止该插件，以后再说。
