Oh! Just seen it by accident. Under ‘CUSTOM’ on the themes page you select which page to show: index or one of your other pages.
ANSWERED!
Now I am ready to add my content. I stropped the lot of junk off the pages and the menu too.
I would still like to know how to convert the side menu to a horizontal menu, or how to call my own menu from this file, instead of from my header.
Do I edit the file ‘sidebar.php’?
