I have been using revolution slider but have noticed i cant access any of the premium features.
my theme has been registered and revolution slider installed and activated, please see screenshot;
Purchase codes (license keys) are not included for plugins that are bundled into the theme. It’s because of the Themeforest license & agreements. This applies to all themes, of course. However, there is no need to use this code because the plugins are fully functional without it.
Something like the “Free” version of a plugin does not exist. All bundled plugins are included with extended licenses, and users can use these plugins within the theme without needing to purchase them separately, but they are not premium plugins. This is standard and according to ThemeForest rules.
More information about the bundled plugins, you will find in the link below:
