Hello and thank you for your answer.
In fact, to better explain to you, we use a plugin to rate our products. (review system that we manage from the product administration: backend).
This plugin, once configured, must display the result on the “single product” page of our online products.
However, using “product builder”, the display of the result of these reviews is not automatic.
To do this I should logically use “block HTML” to integrate and display the result of this plugin (reviews).
The developers of this plugin maintain that the solution comes from the theme used and is not due to the plugin itself.
So my question is: how to integrate and display the result of these “reviews” in an “html block” or by adding a “compatibility code in the “functions.php” file of the child theme used.
I hope to be more explanatory and precise on my request.
Thank you in advance for considering my request in this regard. Not mastering the code used by the theme, I can’t solve this problem on my own.
