A page name is simply "products" or "about_us" or "contact_us" when you save them in BV.
When published, they become "products.html" / "about_us.html" / contact_us.html" automatically.
To be accessed on the internet, you need to type in your browser address bar: "
http://yourdomain.com/products.html " .
In your menus, to be able to properly link your pages, type the FULL url as above.
It will also work with simply "products.html" because the browser adds the ne cessary prefix, but as a good rule type the entire address.
