We’ll get it working, might just take a few steps ??
I’m visiting the site now, and while the child theme is installed it looks like it’s not active yet. Try making it the active theme via the Appearance menu.
When you make the child theme active, Ignite Plus will still technically be the active theme. The only changes will be that the WooCommerce page should now display the products, and you may notice your Customizer settings change back to the default (i.e. the red will return to orange).
On child theme VS parent theme customizer settings
The Ignite Plus Child theme will let you save new settings in the Customizer. You can always reactivate the Ignite Plus theme and your previous Customizer settings will come right back. WordPress just keeps these settings unique for each theme (a bit weird, I know).
The Customizer Export/Import plugin can be used to quickly transfer your settings from the Ignite Plus theme to the Ignite Plus Child theme. This will include the colors you’ve chosen, the social icons, etc.
