Does you theme support Visual Composer?
The Jobify theme only has minimal support for the Visual Composer plugin. Despite this, we do not recommend using any page builders with the theme.
The Jobify theme has been built to use widgets to build pages, for example, the home page and job posting pages are controlled by custom widget areas and design elements can be arranged in any way you wish. This replaces the need for page builder plugins.
There are many different designed widgets to make up a different design on pages such as the homepage, job, resume, and blog page. More details on the widgets available for the Jobify theme can be found here: http://jobify.astoundify.com/category/370-widgets
