Spreadsheet app shos blank browser screen

Hello,

I’ve tried to install the spreadsheet v2 on IIS. I ran index.php, pointing it to a MySQL database running on Apache, with client version libmysql - 5.0.95 and PHP extension mysqli. index.php brought up 01_simple_init.html, but the browser (in both Firefox and IE11) screen is blank. The code behind looks like this:

Why don’t I see the spreadsheet displayed, please? Thanks.
