Well, there is a domain (pietrofarese.net) on witch I began, at first, to develop the site using the Specular Theme.
Then I chose to develop my site with Generatepress theme.
When I changed the theme I deleted evrything in the domain via WordPress (plug-in Advanced WP Reset).
Now, it seems, in the developement area, I have the new site with Generatepress but on-line there is the version “Specular theme”.
Just for your understanding, on-line, the home page is the old version but, in the pages, the footer is the new one.
