Thanks for the link…I looked and sure enough your child theme is not active. When using a child theme, you have to activate the child theme while at the same time that the parent theme (the original theme) is installed, but not active. This means also that when you activate the child theme, you will have to redo your theme options because WP sees it as a new theme activation….some of the “joys” of using WP. B)
Generally a good idea if one thinks at some time down the road they will modify the theme, it’s best to install and use the child theme right away.
