How to resolve 401 Unauthorized in SharePoint 2013?

Question

I am working with SharePoint On premises environment.

I am facing a very strange issue while using the SharePoint site.

Whenever I open any URL it automatically insert following string the URL

_layouts/15/start.aspx#/

Example, when I open Site Content, the URL should be like

http://URL:PORT NUMBER/_layouts/15/viewlsts.aspx

But it always takes as

http://URL:PORT NUMBER/_layouts/15/start.aspx#//_layouts/15/viewlsts.aspx

And due to this I always get the following message

And when I remove the unwanted string then it works fine.

Any resolution to this or any reason why it always take the URL like this?

Answer 1

You are noticing the URL with _layouts/15/start.aspx because the feature Minimal Download Strategy is activated on your site.

If you don't want _layouts/15/start.aspx to be a part of your URL you need to deactivate Minimal Download Strategy feature available under Site Actions -> Manager Site Features
