Is it possible to hide articles for mobile phones?
The fpss is too big for the template and the 2-column-random articles also.

Articles I am afraid not but modules like the FPSS and random articles, sure.

Just use this module suffix: hide-on-phone

The module positions are included in an article. So it won`t work, I guess.

If it supports module suffixes (which I think it does) it will work.
Just insert that suffix in your module's params.

I`ll try this later.
But I think, there will be an empty artcle then.

Anyway, it`s not very important.
In general, I want to thank you for your help.
It is really amazing support and I see an end of optimization of my template, so that i can begin to start with the content of my website.
If I did this on my own, it would have taken weeks. For you it was just a few minutes.
I will recommend your service.

Robert thank you, I really appreciate it.

You mean you published an article with only a module in it?
Have you tried the nuBlog_Component position?

Yes, it`s just an article with the module.

No, I didn`t try . What is it?

Probably I`ll leave it, like it is.

It is a position above the component area. Try publishing your module on this position.

Ok. It works.
But now, there is the problem that fpss is suddenly appearing not only at the home page.
I can see it above some articles, too. Although in module options it says that its only visible at the starting page.

This is a setup issue. All views (joomla categories, newsfeeds etc) that do not have a parent menu or do not belong to a menu item will render through the homepage.
