I've gone through all of these steps and still getting the script errors - I event reinstalled QB.  One of the errors shows this URL: https://s.go-mpulse.net/boomerang/AEN8U......there are about 4 errors that pop up before I can get started working in QB.

I've been using QB Acct 2021 along with other versions for years and this just started happening this morning.  I've also had Chrome as my default browser during this time and no issues.  

Not sure what to do and don't relish spending an hour on a chat with Intuit.  Thoughts?
