Great plugin, but it doesn't seem to recognize child themes, at least not when using Genesis platform with a child theme.
When activated the category will default back to Genesis but won't recognize the child theme. Also, it forces your main site back to Genesis and won't allow you to adjust it until you de-activate the plugin. Seems to work great with other themes, however.
Hopefully this can be corrected especially considering the popularity of Genesis and other theme platforms.
