Update WPBakery Page Builder bundled with WordPress theme

WPBakery doesn't always update together with the theme. In case it's staying behind, do the following: 

• Update the theme
• Access the plugins menu
• Deactivate WPBakery Visual Composer
• Uninstall WPBakery Visual Composer. No worries, all content is in the database, you won't lose any content. 
• Go to Appearance > Install Plugins in the WordPress back-end
• Install WPBakery Page Builder
• Activate WPBakery Page Builder
• When using a caching plugin: clear the cache
