Error 80020101 after upgrading to TFS 2012 Update 1

Now that TFS 2012 Update 2 is on the way, I upgraded my local TFS to Update 1.  I know I should’ve done it earlier but between the holidays and being busy I completely forgot.  The upgrade process was really simple and as I was going around looking at new features on IE, I found that my TFS Web Access site was not responding as I was expected.  Pop-ups were not popping up and I couldn’t exit out of some of the pop-ups that did pop up. 

I kept clicking around and I ran into this error:


It was odd since the site was coming up with no problem on Chrome. 

To fix it, I went to Developer Tools (F12) –> Cache –> Clear Browser Cache. 

Now everything works again!
