Since version 3.0 cherry team decided to move all functionality outside a theme. Now all functionality will be located in cherry plugin. Theme will serve only as a color skin.
In version 3.0 we moved all widgets and shortcodes to plugin. This plugin will be installed and activated automatically on framework update. More features will be added in future.
There can be issues if you have write restrictions for the 'wp-content' directory.
So if you have issues installing plugin you can install it manually downloading it on GitHub.
