If you follow the advice in the title, then you won’t go through the headaches that I am putting myself through. I finished the code for my Archives and Index pages and turned my head back to a custom theme I started three years ago. After looking at some of the files and comparing them with the current themes, I thought, “never mind.” I decided to just use the most recent built-in WordPress theme, TwentyThirteen, and make it work for me.
So I changed the theme on my page and I immediately don’t like it. It takes up the whole screen which is a really old way of doing things. And it’s just generally big. I can’t describe it any better than that. I added my Index and Archives pages to it and they reacted weird, too. Nothing major, just not quite right.
Luckily for me, I have a friend who works with Go Daddy, and spends most of her time talking to people about WordPress, and she reminded me that I can create a child theme and save myself a massive headache. So that is what I will be working on for the foreseeable future. Once I change my live theme back to TwentyTen, that is.
