Why sometimes when visiting a page with an DMX instance sits on, it pops up an "Authentication Required" box. And could not proceed to view the page even all the permissions are correct. And if clicked No then "401 - Unauthorized: Access is denied due to invalid credentials" occurred. I searched around and did not find the right solution. Could you shed some light please?
