401 Unauthorized errors on SharePoint 2013

In my SharePoint 2013 development environment I found a new issue which was not happened in past, I suddenly ran into 401 unauthorized errors.
Those errors would occur only when the pages would be rendered through the /_layouts/15/start.aspx page. This specific page is responsible for loading pages from a site using the Minimal Download Strategy feature, a new feature in SharePoint 2013 that improves client rendering performance and fluidity for navigating from one page to another page by downloading only the changes between two pages.

Error:
401 unauthorized

Solution:
If you are experiencing those 401 unauthorized errors, simply disable the following feature for now.
Site Settings > Manage Site Features > Minimal Download Strategy (see the image below)




Happy SharePointing...!!!
