Thanks egado! I understand perfectly what you mean, but how do I do that? (I am completely new to WordPress, so forgive me if this is a stupid question).
What I want to edit specifically is home.php.
I’ve read on several forums that what I need to do is copy the file by ftp server from the parent theme to the child theme, but this is a dead end as well: I downloaded FileZilla and got my FTP access information from Bluehost, so that’s all good; I can even connect to the FTP fine, but that’s as far as I get. Here’s where I get lost: once I’m connected, it says “Empty Directory Listing” on the right hand side for the remote site. So I don’t know what to copy or where to copy it, because there’s nothing there.
