Web Hosting - Custom Error Documents
Custom error pages (such as 404 File Not Found or 403 Forbidden) allow you to display a branded, helpful message when a visitor encounters an issue on your site. Standard server error messages are often technical and unhelpful; custom pages improve user experience by guiding visitors back to working content.
Please refer to Plesk documentation on configuring and Customizing Error Pages for Windows/IIS and LAMP (Linux) hosting accounts in the Control Panel
Windows/IIS Accounts:
You also configure custom error responses within ASP.NET web.config file.
LAMP Accounts:
You can also configure custom error responses within .htaccess file to specify error locations with the Apache web server.
