Question

所以，长话短说，最新版本的Apache在我的特定设置中导致了一些错误，所以我快速实时升级到PHP 7.1.6，换成了mpm-event，并开始使用PHP- FPM。我想它也可能在某处重新安装了MySQL。

升级后，我的WordPress网站的前端似乎相对较好。管理仪表板有时候还可以 - 但是经常尝试发布一个新页面，或者做类似的事情，它会无限期地挂起。如果我重新启动Apache，它会重新引起注意，但重新启动服务似乎就是诀窍。

在此期间，我的网站的前端也将开始挂起，直到我重新启动Apache。

显然，我的配置在某处出现了问题，但我确实很难确定它是什么。我的网站的前端非常快，直到我在后端做了一些事情，决定将它全部停止。

我一直在检查我能想到的每个错误日志，但是当发生这种情况时，我发现apache2错误日志中没有发生任何事情。据我所知，我启用了PHP-fpm错误记录，但我也没有看到任何显示。

我怎样才能弄清楚此时出了什么问题？

真的很感激任何帮助。我已经花了至少十五个小时试图弄清楚这一点已经没有进展。

谢谢，伙计们。

Answer 1

转到＆＃34; wp-config.php＆＃34;并设置＆＃34; WP_DEBUG＆＃34;如下例所示为真：

define( 'WP_DEBUG', true );

现在刷新前端和后端页面，以便能够看到PHP错误。

您还可以转到管理区域，设置，永久链接，然后再次点击＆＃34;保存＆＃34;按钮。这将覆盖.htaccess文件。

您可以安装日志服务，在google上搜索logly或sentry。那些也可能有所帮助。

Answer 2

我今天注意到我的服务器正在报告Apache的可用更新。我有点困惑，因为'apache2 -v'在此次更新之前和之后都显示了2.4.27。但不管它解决了我的问题。

或许与CVE-2017-9789有关。
