Yes, I did create a new folder for the new theme (as per step 2 of the directions). The PhP file was in reference to step 3 of the directions (below). I did also change the Stylesheet in the spTheme.txt (as per step 4): I have tried it both with a hyphen between the name and the word ‘theme’ and all one word. (NB: I did not name it ‘my-theme’, I named it after the blog; does that matter?)
I did all the steps I understood from the ‘creating a theme’ page http://codex.simple-press.com/codex/themes/theme-basics/creating-a-theme/:
1) Double Check Where your Themes are Located
2) Pick a Theme to Copy and Create your New Theme’s Folder
3) Rename your custom theme’s filename:
Within your newly copied folder there will be a ‘styles‘ sub-folder and in there is your main theme file. This must have the same name as the theme so – using the above example – rename ‘default.php’ to ‘mytheme.php’.
4) Edit the spTheme.txt to name your Theme
In your new theme folder is a file names ‘spTheme.txt‘. You need to edit the header details of this text file and change the theme name to your new theme’s name.
Open up the spTheme.txt file and change the two lines pictured below to the name of your theme and the php file name. Note that if you are copying a CSS only theme then this must point to the CSS file.
For example change “Simple:Press Theme Title: Default” to: “Simple:Press Theme Title: mytheme” and Stylesheet: default.php change to Stylesheet: mytheme.php
5) Edit the Functions Template to Change Localization
Open spFunctions.php with your editor and change the function names to match your new theme name. If you used the default theme as your starting point then replace all references to ‘spDefault’ in your theme’s name. Please note there may be several occurrences of the theme name in this file. They must ALL be changed to the new name.
