Search page product list does not follow the Page Grid Journal style

My site is https://ferramentaevernici.it/index.php ... ommon/home.

If you try to search something like "Maniglie" :
https://ferramentaevernici.it/index.php ... ption=true
You have that the product list does not follow the Page grid as you can have if you select "I nostri prodotti" and select any choice.
In fact, changes in the product grid/list in Journal/styles and product listing skin have no effect.

Giving a look at the Open Card Navigation Panel => Design => Editor Theme => product/search.twing, the part of code related to the search page product list is
<div class="main-products product-{{ j3.settings.get('globalProductView') }}">
{% set display = j3.settings.get('globalProductView') %}
{% include "journal3/template/journal3/product_card.twig" %}
</div>
There is a reference to product_card but I can't find it in Navigation Panel => Design => Editor Theme => journal3.
Where is this file?
The error occurs after I made some changes to product/search.twing but then, even if i try to reset the content of this file, nothing is changed.
What is the issue? Why it work before and now no more?

Thanks.

That's not an Opencart Problem, and for Journal-Themes in general, you have to contact Journal Support on this, because this Theme Extension is not supported here.

it is no a Journal theme issue, but a question about Opencart
it is a Search Page issue.
it is a different behavior respect to other product page/list.
it seems something is corrupted

The location of the file depends on your OpenCart version. I not even sure which version OpenCart Cloud uses. You may not even be able to access the files on OpenCart Cloud.

If you do update a theme template, you may need to refresh things like the theme cache and the modifications.

My OC version is 3.0.2.0
I tre to reset the product/search.twing file
Then, I go to Extention>Modifications> push reflesh botton
Then, i went to DashBoard > Developer Setting Action > push the orange button Action
However, nothing is changed

The search results are normally listed in the catalog/view/theme/default/template/product/search.twig , and the visual layout can be modified to a grid-style listing via the stylesheet at catalog/view/theme/default/stylesheet/stylesheet.css .

However, since you are using the Journal3 framework, and not the OpenCart framework, this doesn't apply in your case, and you'd have to contact the Journal3 support on this. Or better, use a nicer standard-compliant OpenCart theme.
