Install the widget on WordPress

This guide uses the JustReview Testimonials widget as the example. Every other widget works the same way.

Add the library to your theme

1. Build your widget and click “Generate Code for your website”.

   

   

2. Open the theme editor: Appearance → Theme File Editor.

   

3. Edit footer.php and paste part 1 and part 2 before the closing </body> tag.

   Part 1 loads the library and belongs on the page only once, even when you display several widgets. Part 2 is the configuration for one widget, so add one part 2 per widget.

   

   Save with Update File.

Theme updates overwrite this file

Editing footer.php directly means a theme update can wipe your changes. Safer options: use a child theme, or a snippet plugin such as WPCode that injects code before </body>.

Place the widget on the page

Part 3 of the snippet is the container that decides where the widget renders. Pick the method that matches how you build pages.

Theme template

Paste part 3 into the template file at the spot where the widget should show up.

Post or page

Add a Custom HTML block (or switch the classic editor to the Text tab) and paste part 3 there.

Elementor

Add an HTML widget to your layout, then paste part 3 into it.

Divi Builder

Divi needs the three parts split across different places.

1. Add a Code module inside a new section and paste your container <div>.

   

   

   

2. Add the library files (part 1).

   

3. Add the JustReview configuration script (part 2).

Do not forget to save.

The widget will not show in wp-admin

The widget only renders on domains listed in your Settings, so the WordPress admin preview stays empty. Save your changes and check the live site instead. Your website address must match the whitelist entry.

Regenerate the code after every change

Widget settings live inside the snippet on your site. After changing anything in the dashboard, generate the code again and replace part 2 on your website.

Widget still not visible?

Work through these in order, they cover almost every case:

1. Domain whitelist in Settings matches your address.
2. Part 3 (the container <div>) is present on the page. Without it there is nothing to fill.
3. Caching plugin. WP Rocket, LiteSpeed Cache and similar tools cache the old HTML and can defer or combine JavaScript. Purge the cache, and exclude justreview.js from JS optimisation.
4. Part 1 appears exactly once. Loading the library twice can break rendering.
5. The Badge widget needs at least one review before it shows anything.
