In QuickBooks on the menu bar click HELP>Internet Connection Setup>Next>Advanced Connection Setting>Security (tab)>Restricted Sites>Sites. In the "Add this website to the zone:" paste or type url address the error message is complaining about, such as uxfabric.intuitcdn.net, as an example. Click Add>Close>OK>Done.
Logoff QuickBooks and then log back in. The script error message will no longer appear.
This can be used for all script error messages when opening QuickBooks. I have encountered several. They all seem to be connected to "User Experience Enhancement" (aka User Tracking) that are not functioning correctly. Blocking them does not affect the software....other than to block some pop-up ads Intuit may try to send.
You can answer YES or NO to get past the script error message if you are not bothered by it and do not want to take the above action. It does not affect QuickBooks one way or the other.
