Health Check & Troubleshooting

Description

This plugin will perform a number of checks on your WordPress installation to detect common configuration errors and known issues, and also allows plugins and themes to add their own checks.

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 clean WordPress session, where all plugins are disabled, and a default theme is used, but only for your user until you disable it or log out.

The Tools section allows you to check that WordPress files have not been tampered with, that emails can be sent, and if your plugins are compatible with any PHP version updates in the future.

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.

Feedback is welcome both through the WordPress.org forums, the GitHub project page, or on Slack in either #forums or #core-site-health.

If you should find your self stuck in Troubleshooting Mode for any reason, you can easily disable it by clearing your cookies.

Are you unfamiliar with how to clear your cookies? No worries, you may also close all your browser windows, or perform a computer restart and it will clear this specific cookie automatically.

The PHP compatibility says this plugin only work with PHP version X?

The plugin is made to be a support tool for as many users as possible, this means it needs code that is written for older sites as well.

Tools that check for PHP compatibility do not know how to separate this code from the real code, so it will give a false positive response.

At this time, the plugin has been tested with every version of PHP from 5.2 through 7.3, and works with all of these.

Where can I report security bugs?

Nobody seems to care

This plugin adds many valuable features for site administrators to WordPress Core. I installed and used it on all my sites for years.

Since half a year though, there is security issue (CVE-2025-64253), and nobody cares to address it. Clients start to complain about that unsafe plugin, so I had to remove it.

I can’t believe that

By مؤسسة دعسه برو (abuwassan) on April 4, 2026

I can’t believe anyone gave this plugin 5 stars. Troubleshooting mode will break your site. It disables ALL plugins and it says that this will only affect you and NOT your other site visitors but that is FALSE.

When you disable troubleshooting mode all plugins remain inactive! There is NO WAY to revert or cancel this. Once you enter troubleshooting mode you are screwed.

My entire site was broken and I had to scramble to reactive plugins one by one.

Authors are slow to fix issues

By kal123 on September 8, 2025

This issue has been open for almost a year and not fixed:

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the health-check domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.
