www.wysiwygwebbuilder.com

Hello ! This is my first message on this forum. And it's also the very first site I do in my life. And of course I do it with Wysiwyg Web builder. I just tried to put it online, but it does not work. The preview without a browser works perfectly. When I opublie in a folder of my computer, it works very well too.
The structure of my site is as follows: There are three folders:
home
French
English
with in each folder the elements necessary for the site. When I use the publish button, everything goes well but on the site in the www folder (I am hosted at OVH) I find all three folders. But since there is no visible index.html file, it can not work.
How should I do it ? Should the files be deleted?
Thanks for your help.

The 'index' page should be in the root of your website.

Thank you Pablo. I changed the structure of my site. I deleted the Home folder so that the elements are at the root of the directory. What deceived me was that the preview worked well. Many thanks for your help.
