Your previous theme (Jupiter) had “visual composer” plugin bundled within the theme. It is “not” recommended, as user tends to lose all stuff added via visual composer when changing themes (like in this case). To create such pages explore either of the following option:
1. Free page builder by site origin – https://wordpress.org/plugins/siteorigin-panels/
2. Visual composer plugin – http://codecanyon.net/item/visual-composer-page-builder-for-wordpress/242431
