Kadence - Installing a Kadence Child Theme
Installing a Kadence child theme is just like installing any other theme. Because it is a child theme it's required that you have Kadence installed.
You may notice a slight delay in load time while the theme is installed. This is totally dependent on the hosting company you use.
If you have the "Classic Editor" plugin installed, you need to uninstall it to make the theme work OR enable the Gutenberg/block editor in the plugin settings
