After installing the theme you most have to install the ‘Appart Core’, ‘Elementor’ , ‘Rredux Framework’, ‘WooCommerce’ and ‘CodeStar Framework’ plugins to import the demo content as well and work the theme correctly.

You will find all required and recommended plugins to Appearance>Install Plugins.

Note: Install the WooCommerce plugin if you want the shop page. Otherwise, you no need to install this plugin.
