OK, so I clicked on the link that explains how to create a child theme. It says to "Create a directory in your themes directory to hold the child theme. The themes directory is wp-content/themes. You should name the directory without any space as part of the name, and it is common practice to use the name of the parent theme folder with “-child” appended to it. So, for instance, if you are making a child of the twentythirteen theme, your folder name would be twentythirteen-child."
I am stuck on step #1 - "the themes directory is wp-content/themes." Where is this? I have absolutely no idea where the themes directory is to begin with.
And I don't mean to bump - I didn't realize I was doing that. And I would happily hire somebody to do this for me if I had a clue of where to find such a person. Not a website that will make me sit on hold for hours or require only live chat. And no, it isn't that urgent, it is just enormously frustrating.
