The Ultimate Reviewer comes bundled with the WPBakery Page Builder plugin. While you can use Ultimate Reviewer without this plugin in the form of shortcode, it is not recommended as the default review templates will not work.

Step 1: Go to Appearance > Install Plugins.

Update Through Theme
When a new WPBakery Page Builder plugin update is released you will need to wait until the Ultimate Reviewer update is available which will include the updated version of this plugin. To update the plugin do the following:
Step 1: First you need to update the Ultimate Reviewer as described in the Updating The Plugin section.
Step 2: Now go to Appearance > Install Plugins, find the WPBakery Page Builder and click Update.
