Folders & files Not Visible with Admin login

Hello everybody,

First of all, thanks for all the provided information in this topic. Very usefull.

Usefull, but some cases are still not fixed. Example: in my case:
-when typing the device name on the adress bar, it is resolved but i don’t have a credentials pop-up to be filled in.
I directly reach the folders page

Problem is that data folders can not be seen.

so questions: how do i do to get the credentials prompt and to display the data folders?
is this situation related to the fact that i did not log in?

Many thanks in advance for your answers
Steven
