I have a local setup that runs in visual studio and for some reason the back office is always blank... before it was just the admin so I upgraded and now it is doing it still but redirecting to a blank http://localhost:52277/umbraco/AuthorizeUpgrade? page.. Why would it be blank? There is html there but it isn't displaying?
What version did you upgrade from? I'm assuming you upgraded to the latest release? When doing the upgrade did you do that manually or using nuget? And did you check to see if there were any specific upgrade instructions that you needed to take care of manually?
The reason for the blank screen can be caused by JavaScript errors due to caching issues, cookie issues etc.
If you look in the console log of your browser does it then throw any JavaScript errors? And also if you look in the /App_Data/Logs folder does that reveal anything marked with "ERROR"?
After running an upgrade Umbraco performs some database migrations, which are triggerd by "Authorizing" the upgrade when logging back into the backoffice. But for some reason it currently can't run in your case obviously :)
Without more specific knowledge of why it's failing I would try the following
Clear you cookies - Does that make any difference?
Go to /AppData/Temp/ClientDependency and delete all of the files
in here - Then go to the /AppData/Config folder and increase the
version number attribute by 1 and then finally recycle the app pool.
Does that make any difference?
I just ended up starting a new project and re-setup everything and it's working now... weird... Cause it have been caused by me letting nugget update web.config etc during the upgrade?

I hope these pointers help and make sense :)

I have looked at the javascript console in the browser (I have tried IE, edge, Chrome and safari) and there are no javascript errors..
I used Nuget to upgrade..
I tried your steps to no avail..
Hi Kris,
Do you have any redirect rules in place? They may be in Web.Config if your web.config is very similar to your live environment.
The backoffice being completely blank when serving that page is quite unusual.
Have you checked the log file in App_Data that Jan suggested?

...And also...what version did you upgrade from? Perhaps something needs to be done manually :)
