I am facing a really weird issue and can't figure out what is going on here. An internal menu item (added by clicking 'Article') was unpublished and I was expecting the 404 to be generated. But when I click in the in page link, it is generating the following URL structure (which I suppose is the Joomla router trying to create an URL)
And the HTML content of the page displayed is as the follows.
<html> <head> </head> <body>View not found [name, type, prefix]: 11new-books, html, contentView</body> </html>
What could be happening here for it to not even display the error page?
