You can read more about child themes here: https://codex.wordpress.org/Child_Themes and the video goes over naming as well: http://kriesi.at/documentation/enfold/using-a-child-theme/

The answer to 1,2, and 4 is in my response above: you would need to change the name of the theme folder and the name of the theme in the style.css folder.

For 3, you can’t have two themes with the same name, even as parent:child themes.

Hey DavyE!

Try updating to the latest version of Enfold (there is a new one: 2.6.1).

Best regards,

Hey Gabriel!

Are you using the latest version of Enfold (2.6.1)?

Cheers!
Josue

I think it would be better to do most of the changes in the visual editor.

Also, the latest version of Enfold is 2.6.1.

Cheers!

Hey!

Try adding this code to the Quick CSS:

#header_main .container {
    height: 80px !important;
}
.logo, .logo a {
    height: 90% !important;
}
.site-description{
    bottom: -22px;
}

@media only screen and (max-width: 767px) {
.site-description{
    bottom: 5px;
    left: 55px;
}
}

Cheers! 
Josue

Hey!

The icon shows up when you don’t have a featured image on that post. You can also change the blog layout to one of the alternate styles if you don’t like that layout (in theme options>general settings).

At this point updating you would need to re-upload the whole theme and overwrite everything that was there before. This will bring you up to date with the most recent WordPress changes and add in all of the new features that have come out over the past few months.

The current theme version is 2.6.1 which came out this past week. With the number of changes that have come out in the past (almost) year now you will likely need to re-do some content areas to work with the new features. See: http://themeforest.net/item/enfold-responsive-multipurpose-theme/4519990#item-description__changelog
