I changed the original functions.php and added two new array under the existing one. One named Sidebar1 that I’d created and one named sidebar2 … when I swopped to child theme my site went blank.
I then created a blank functions.php but just copied the following into it.
That didn’t work, but at least the screen didn’t go blank! I know a little knowledge is dangerous, but I’m hoping I can learn by trial and error, so what has this thicko got completely wrong?
