The status code 404 or ‘Page Not Found’ error message is a common HTTP response code that occurs when you follow a broken link.
In WordPress, a 404 error, also known as “page not found” error, is displayed when a requested page or resource on the website is not available or can’t be found. This can happen for various reasons, such as when a page or post has been deleted, moved or renamed, or when a user types in an incorrect URL.
When a visitor encounters a 404 error, WordPress displays a default error message, but website owners can customize the message using a plugin or editing the theme’s 404.php file.
It’s important to monitor 404 errors on your website to identify and fix broken links or missing content that could negatively affect the user experience and search engine rankings.
