Qlue Custom 404
The Qlue Custom 404 component detects when your website has a page error and redirects a user to your own custom 404 error page. The component will redirect any HTTP errors including 404 Page not found, 403 Forbidden and 500 Internal server error.
This means you can improve on the ugly standard error page and generate an error page that's user friendly, navigational and even include a search box to help direct the user to the page they are looking for.
Return the correct HTTP error (many other extensions do not do this and it's important for SEO!)
Detect errors (eg 404 Page not found) and display a custom page in your own template
Custom error page can include modules!
