Activating Revolution Slider and WPBakery Page Builder licenses
You can not activate Revolution Slider and WPBakery Page Builder licenses because you don't directly buy them. We bought them with our account (Extended License) and integrate them into our theme.
You can use them normally without activating the license key.
We include the license keys in the theme package because we want you to know that we bought them and you have permission to use them.
When they release a new version, we will update and integrate the new plugin version into our theme.
