Customizr Pro / Hueman Pro and WordPress Multisite Network

Q : I am developing a Wordpress Multisite. In regards to the purchase of the Customizer Pro, will it work with subdirectory blog sites? Is the price for one website applicable to my Wordpress multisite?

As a network administrator, you can install Customizr Pro for the network, and activate a single activation key. You don't need a multisite key.

Once you've installed and enabled Customizr-Pro as network theme, just go in one of your subsites dashboard and you will be able to find the Customizr-Pro theme among the available ones, set it as active theme (move your mouse over the theme image and click on Activate).
Once done, you should be able to see the Customizr Pro Key menu item under the Appearance menu.
