No way, I reinstalled the theme manually but the result is the same.
I notice there is only a little change if I select “show latest articles” and not “static page” (here is the screenshot http://www.fucina798.com/wp-content/uploads/2013/01/creativix-with-latest-articles.jpg), the slideshow appears.
I tried, but I surely am a kind of a dummy and maybe I uploaded the files in the wrong directory messing with Filezilla… chaos! And shame on me.
I ended re-uploading entire WordPress on my server. I reinstalled automatically Creativix but the problem remains.
I am going to try again with manual installation… sorry.
