it is trying to find your page as index.html so rename your homepage to index.html
when you sign up for a domain or the free subdomain site you are given a placeholder index.html page and all YOU do is publish your index.html page to replace it
don't delete the page or do anything else UNLESS you save your pages as .htm in stead of .html
then you would delete the index.html page from your file manager so your index.htm page in your ROOT directory will show
I published my homepage as home.html then saved it. For every other page that I am trying to add to my website, I am downloading the template that I want to use, renaming it to the name of the page, example it is a church website, I have home.html, Ourpastor.html, etc.....but when I save them after editing them in the visual editor, it does not allow me to see the website at all.
