Calendarize it! was originally created without support for WPBakery Page Builder (formerly Visual Composer). Please notice that you do not need WPBakery Page Builder to use Calendarize it!, but if you have WPBakery Page Builder you can take advantage of the built-in compatibility with this plugin and build your own templates using the popular drag and drop page builder.
TO MAC USERS: If RAR password doesn't work, use this archive program:
