I checked your website and I also see a blank page.
Looking at your code, it’s not exactly surprising. The index.html you uploaded contains a few tags, but no content at all. So nothing will be shown on the page.
I do see a folder with files that seem to be from WordPress Duplicator. I’m not familiar with how that plugin works. So please check the information from Duplicator on how to restore your website with that.
Or follow our website migration guide instead.
But as troublesome as WordPress backup/migration plugins tend to be, Duplicator at first sight seems to be promising because you can manually extract their archive instead of having to send hundreds of MB of proprietary format backup to a web form and hope for the best.
