Hi Vekia,
Thank you for your answer.
I installed the module you have mentioned. The products total per category is great, however it is still presenting top categories from other then the one I have clicked.
I'm trying to list all subcategories of a top menu category, which have products associated. The blockcategories2 module shows every categories, even all top categories, with products count, and with the suggested change, no categories without products will be shown.
After reading about modules creation, and not having the chance of overriding modules, yesterday I started to build my first module, with the hope of finding an answer to my quest. Maybe it will turn on my first contribution to the community.
Kind regards.
