A QuickBooks Script Error will appear when you try to access a web page from within the QuickBooks software. There are several possible causes for this.
If your browser isn't set up to work with QuickBooks, you could end up with an issue with your company's finances.
If the page request is made when Internet Explorer is already open, a QuickBooks script error may occur.
Wait for the error to appear unless QuickBooks is synced with Internet Explorer.
