The file you have requested does not exist

The website uses Inline Google Spreadsheet Viewer on two separate pages – using the importrange function within the spreadsheet. These have been static pages for many years – with pages existing and access available set to public. In June, we changed from http to https – and since then – the website has displayed the error message. Updates have been performed monthly.

The page below – has been created – the first spreadsheet on my page is your “Inline Google Spreadsheets Viewer example spreadsheet”

Any ideas? We really need to resolve this or find another solution
