I'm at work, on the corporate network using SSO. The last few days, I haven't been able to login to the portal using Windows 10 & IE11. I go to portal.azure.com and go through a few redirects and get stuck athttps://portal.azure.com/signin/index/ which is a blank white page. If I look in the IE11 debugger, it shows:
SCRIPT5007: Unable to get property 'getItem' of undefined or null reference
index (10,54)
Works in Edge and Chrome. I've cleared my browser history, including cookies, rebooted, system restore back to last week when I know it worked. I've also gone into Credential Manager in Windows and deleted the SSO credential. No matter what I do, it gets stuck on that signin/index page which is a blank white page.
How can I fix this?
