A staging website is useful for the debugging process. Having a Staging website, all the debugging can be done safely, without affecting the live website.
To create a staging website, you will need a 3rd party plugin called WP Staging.
Note: Some hosts might include a service in your hosting plan that allows you to create a working clone of the live website. So, before creating a staging website, check with your hosting to see if they offer such a service.
Installing the WP Staging plugin
Go to WordPress Dashboard → Plugins → Add New
Search for WP Staging
Install and activate the WP Staging plugin
Create a staging website
Go to WordPress Dashboard → WP Staging
Click on Staging Sites → Create Staging Site
Give your staging website a name.
Click on the Start Cloning button.
Note: Depending on the size of the live website and the speed of the server, a complete clone of the live website takes, on average, 2- 10 minutes.
Once the cloning process is complete, click on the Open staging site button.
Notes:
The login details (username and password) for the staging website are the same as those used on the live website.
