My site – 12field.com.au, I'm using WordPress 3.6, referencing a theme called Ronika.
As it’s best practice for modifications, I've set up a child theme. I have created a new folder in the Themes folder, and named it 12field. In that folder I have a new copy of the .css file, ready for my modifications. At the top have this information, referencing the Template and an @import link.
Theme Name: 12field
Author: Simone Bennett
But when I make changes to the .css file in the child folder, nothing happens. If I make changes to the .css file in the Ronika folder, then the changes appear fine. I don't even think Ronika is loading my child .css file at all. It's like it doesn't exist.
The php files in the Child folder change fine.
Been playing with it for hours, I've contacted the theme's developer and he doesn't know.
