Sometimes, when you login to a webpage, nothing is displayed.
This problem is due to the compatibility view of internet explorer.
This also can happens to the Microsoft online portal.
When your http://portal.microsoftonline.com website looks like this :
Only a blue ribbon but nothing else. The complete page is white !.
Select the settings button, and click on F12 Developer Tools
Click on Browser mode: IE10
Select or deselect the Internet Explorer 10 Compatibility View
And there it is !
The page is working fine
