Please read this doc: https://wpforo.com/docs/root/categories-and-forums/forum-layouts/extended-layout/

The way it shows the screamshot is how its seem now. I will like what its under the red cross to dessapear so that the visitor have to click on the topic itself

Is there a way to hide completely the answers to the different topics unless the viewer clicks on the topic?

I managed to hide them completely in the front view of the foro but once you click in a particular foro, I would like to see JUST the different topics but with all answers hidding

Is that possible at all?

*What happens is that many of my already and future members are used to a particular layout for many months and years, and for them (and also for me) any change its sort of "overwhelming" for  a lack of a more appropriate definition

*see attachment if my explanation is no clear

Thanks :)

Try the wpForo Extended layout. 

Which one would you suggest being the closest one to the "simplified" yet giving the members post count?

I just added several forums and subforos...

All I need to do its to change every category correct? I wait for your advice in the more similar layout to simplified. *Simplified was great for my type of users EXCEPT for that number of post count missing... what a pity :)

You should use another layout.

And btw, I add, NOW the forum is working as its normally do, reacting at first hit....  but its been not reacting properly for a god hour at least...

Please attach the screenshot.

But just in case I include screamshot of where I meant that I would like to see the members post count in figures/numbers to show.... :)
