Troubleshooting Mode was initially a feature introduced via the Health Check plugin, and is now available as a standalone plugin.
The most common, and reliable, means of troubleshooting a website using WordPress, is by first disabling all plugins, and using one of the default themes that come with the software. 
The best way to do this, is by the use of a staging website, but not all website hosting providers have this feature, or it may not be part of the plan you are currently on.
Troubleshooting Mode will do its best to allow a site maintainer to disable plugins, and switch themes, without affecting regular visitors to your website.

This simple plugin creates a <code>/health</code> endpoint to let you monitor the status of your WordPress website. The endpoint tests the status of your database connection and returns a <code>200 OK</code> HTTP status code while your page is healthy. You can read more on HTTP status codes at the <a href="https://en.wikipedia.org/wiki/List_of_HTTP_status_codes" rel="nofollow ugc">Wikipedia article</a>.
External tools such as website monitoring services can access the exposed endpoint at regular intervals. This can help you verify that your WordPress website is performing correctly.
