Please check the cases below to fix your issue.
1. You are using a Shopify 2.0 Online Store theme
Our app will not automatically install codes when installing the Ryviu app for your store if you use a 2.0 OS theme, such as Dawn theme. You will need to add Ryviu blocks to the section where you want reviews and stars to appear for your product page template. Please check this instruction to know to install it.
2. Your product reviews are disabled in your Ryviu Products Manager section
If reviews of any product are not shown on the product page, please go to your Ryviu dashboard > Products and enable reviews of the product by turning the status icon green. So reviews of that product will be displayed on your product page.
3. All reviews of your product are disabled
By default, Ryviu will disable reviews if their content is empty and their ratings are less than 3 stars.
Please check if they are enabled or disabled from the Products manager section by navigating to Products > Choosing a product that you want to edit reviews.
Then scroll down to the review section, enable the review you want to display.
4. Reviews disappear on one or some products after importing
If reviews disappear on one or some products after you changed your product handle/permalink on your Shopify/ WooCommerce store when importing reviews, you can easily fix it by following the steps below.
Please go to your Ryviu dashboard > Product
Click on the edit icon on the product you want to update reviews
Update its Handle to the same as the product handle of your product in your store.
Finally, click Save button.
5. Reviews disappear after changing/updating your theme
If reviews are not shown after you update your theme, please refer to the instruction below to install Ryviu snippet for your new theme to make reviews appear again:
6. You are using the 3rd app to create a product layout
If you are using an App to customize your product layout, please add these snippet codes to your app layout to display reviews. Here are code snippets:
- Stars rating under your product title:
<div class="review-widget"><ryviu-widget-total reviews_data="{{product.metafields.ryviu.product_reviews_info | escape }}" product_id="{{product.id}}" handle="{{product.handle}}"></ryviu-widget-total></div>
- Snippet code to display comments:
<div class="lt-block-reviews"><ryviu-widget handle="{{product.handle}}" title_product="{{product.title}}" image_product="{{ product.featured_image.src | img_url: '100x' }}"></ryviu-widget></div>
That's how to do it.
