説明
This plugin will perform a number of checks on your WordPress install to detect common configuration errors and known issues.
It currently checks your PHP and MySQL versions, some extensions which are needed or may improve WordPress, and that the WordPress.org services are accessible to you.
The debug section, which allows you to gather information about your WordPress and server configuration that you may easily share with support representatives for themes, plugins or on the official WordPress.org support forums.
Troubleshooting allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but only for your user.
For a more extensive example of how to efficiently use the Health Check plugin, check out the WordPress.org support team handbook page about this plugin.
In the future we may introduce more checks, and welcome feedback both through the WordPress.org forums, and the GitHub project page.

評価
Easy-to-use and very helpful tool
I’m not a developer but I really appreciate this plugin: It provides all useful data to solve plugins/themes conflicts and returns a very accurate picture of the health of my websites. And it’s easy to use, too, also from a non-expert user like me.
In addition, the debug section allows me to collect all the needed data to pass to my site developer.
Last but not least, I really love the community spirit that animates the team and their availability: thank you, guys! You’re doing a great work!
Simplifying troubleshooting
A quick and easy way to do the first troubleshooting on a problematic website. Saves me tons om time, that I do not have to create a test site before I can turn off plugins and themes.
Highly efficient
A very efficient and quick way of diagnosing the cause of conflicts. The troubleshooting mode is a life saver. I can turn my site upside down (deactivate all the plugins and switch themes) and my live site is not affected in the meantime. I highly recommend it.
The easiest way to troubleshoot problems on your WordPress site!
The Health Check plugin is definitely the best way to troubleshoot issues on live sites. It provides lots of information about your server (software versions, PHP info and lots more) which is super useful.
It will also let you deactivate/activate plugins and themes on your site without disrupting your live site. This means that if one plugin is causing problems on your site, you can deactivate them all until you find the cause of the problem. All of this without your users even noticing!
A must use plugin to find the exact cause of an issue
In WordPress, it is very common to see plugin or theme conflict due to either PHP or Javascript code, etc. To find the exact cause of the issue, I always need to disable all the plugins one by one to check whether it is a plugin specific issue or even switch the theme to the WordPress default one.
It is a nightmare when the conflict occurs on a production site as I don’t want my visitors to see a broken site when switching the theme or a plugin that my site rely on.
So, I found Health Check & Troubleshooting plugin is a must have for me that helps me to troubleshoot the issue without affecting in my site. No one knows whether I’m disabling a plugin or switching the theme except me. I’m happy when my visitors are.
So, thanks to the WordPress community to make a very useful plugin.
A Great Tool for Every WordPress Admin
I came across this plugin about six months ago, and it has been a lifesaver since. It lets you check for theme or plugin conflicts without destroying or harming your site. With the use of the plugin, you do not need to create a staging site to perform conflict checks and it saves time. It seamlessly identifies the plugin causing a conflict
I honestly recommend this plugin.

変更履歴
v 1.2.1
- Make sure only those with access to the plugin see the backup encouragement notice.
- Make sure the
is_troubleshooting()checks are available to the Site Status tester when the MU plugin may not have updated yet. - Avoid a warning of an undefined variable if you have the latest WordPress version installed.
v 1.2.0
- Changed plugin name, it now better describes the plugins two primary purposes.
- Changed the
Health Checktab, it’s now namedSite Status, as we used the old name too many places and it was confusing. - Site status tests now run asynchronously, making the page load much faster.
- The HTTPS tests now also check your Site URL settings to make sure they are following recommended best practices.
- Fixed a warning preventing plugin names from displaying on the front-end in some cases.
- Fixed an issue where you might get a 500 error if you tried using Troubleshooting Mode while using a child theme.
- Automatically disable/enable a plugin or theme in Troubleshooting Mode if they are detected to cause errors.
- Introduce a new dashboard widget during Troubleshooting Mode (and a simplified version on the plugins screen) to better explain what is going on, and make available actions more discoverable than the admin menu is.
- Some text improvements throughout the plugin.
- When loopback tests fail, we previously tested all plugins at once, for sites that have many plugins this may fail as the request times out. We now test one plugin at a time to avoid this, while also showing more information at the tests are running to the end user.
