Hi there. See here: https://www.businessbloomer.com/woocommerce-categories/
Seems that we'd need that config being in place in Customizer, but I do not find/see it. So how could I - without using Elementor, but only standard WooCommerce theme templates - get category pages to list their own subcategories only, and not - which seems to be standard behavior for Bifrost - all products belonging to both mother and child/sub categories?

Thanks in advance for reply, and best regards, e.-

Are you sure you did it? I mean, here we are in the "main" (mother) "Hosting" category, but instead of listing the 4 subcategories, that page lists all the 27 products, taken from any of such child categories (and also mother one).
In next post I'll give you info on local DNS resolver overrides, so to have you pointing to the correct server (the one which actually hosts the development site). Credentials for accessing WP backend will be the same you already have for staging environment. Kindly let me know whether or not you also need FTP access (or phpMyAdmin, via Plesk). Thanks, e.-

Oh, thank you so much! That's so kind of you. Going to apply those additional CSS directives, as you suggested, and then I'll be back to you soon, with some feedback. All the best, e.-

I do confirm that now the pagination issue has been fixed. I've copied the additional CSS from https://neuronthemes.fucine.it/ecm/ (public) and pasted it into http://fucine.it/ecm/ (private) and now http://fucine.it/ecm/categoria-prodotto/hosting-ssd/ works as expected: good sub-categories title size, and no pagination at all. So, in the end, it was simply a matter of ".o-pagination" vs ".pagination". Quite funny! :-)
Thank you SO MUCH for the stellar support. All the best to you all, e.-

This has just been made. As per attached image. You deserved it, sure.
I beg your pardon for not having reviewed it before. All the best, e.-

In effect there are several other issues which might be possibly/hopefully addressed. Let's start.

So https://neuronthemes.fucine.it/ecm/categoria-prodotto/hosting-ssd/ has been fixed, and this is great.
But it seems that any other product category, not being under the "hosting-ssd" one, still presents unexpected behaviour. For example this one: https://neuronthemes.fucine.it/ecm/categoria-prodotto/hosting-sata/ or this newly created one: https://neuronthemes.fucine.it/ecm/categoria-prodotto/test-category/
The first one actually has a product inside, and also the second one. Both categories have "default" type of visualization. In the end: products (inside them) should be listed, and not sub-categories of "hosting-ssd" main category.

Furthermore we now have - which was not present before the overrides via custom shop.php took place - an issue with TAGS also. For example: https://neuronthemes.fucine.it/ecm/tag-prodotto/storage/ Again: products with "storage" TAG should be listed, and not (again!) sub-categories of "hosting-ssd" main category.

Thanks for further investigations (I'm so sorry about this mess with WooCommerce), and best regards, e.-

I beg your pardon for not having replied before: when you wrote I was just leaving my town for Summer holidays. And now that I'm come back I do confirm that all my issues are fixed:

- products (inside categories) are actually listed, and not listed anymore sub-categories of "hosting-ssd" main category;
 - products with any possible TAG are actually listed, and not listed anymore sub-categories of "hosting-ssd" main category.

What else to say? Thank you so much!
All the best, e.-
