Hi guys,

i need your help,

i'm running prestashop and i have a problem with the productcomment module (version 3.5.1).

the module is working perfectly but when i analyze the google snippets with google structured data testing tool,

i get 2 errors for all the products of my shop that have not reviews yet:


  • the field ratingValue cannot be empty.
  • It's necessary to specify ratingCount or reviewCount.


this problem is because google can't see the ratingvalue and ratingcount when there are not reviews...

i know that this problem is linked to the code specified into the file:




into the productcomment folder of my theme (default boot-strap).

i need to modify the aggregateRating [AggregateRating] with a condition into that code that show google a certain value when there are no reviews yet and doesn't leave empty fields, i tried everything but i didn't success, could you please check it ????


here my productcomments-extra.tpl

let me know what i have to do to be able to have no errors into google data structure when i have not reviews.


p.s: the products with reviews have no errrors at all because all requested fields of AGGREGATERATING are correctly filled

Try to replace line 27 with:

<div id="product_comments_block_extra" class="no-print" {if $nbComments != 0}itemprop="aggregateRating" itemscope itemtype="https://schema.org/AggregateRating"{/if}>
