Stefano,
You don’t seem to have activated the plugin at all. There’s nothing referencing it in your “view source” page.

Hi, thanks for answering. Strange, I was sure the plugin was activated. Pleace check now. Cheers. Stefano
Again, you still don’t have our plugin activated.
In fact, we dug deeper and find that you’re somehow mistaking our plugin with another one that you have installed. You can see right here that it’s a totally different developer: http://antartide.mondointasca.it/wp-content/plugins/youtube-video-player/readme.txt
If you had ours, then the following page would exist:
http://antartide.mondointasca.it/wp-content/plugins/youtube-embed-plus/readme.txt
If you plan to use our plugin, we suggest that you deactive any other YouTube plugin first.

This is getting crazy. Is it this your plugin:

Is it your shortcode:
[embedyt]http://www.youtube.com/watch?v=ABCDEFGHIJK&width=400&height=250[/embedyt]?
On my page you have exactly your shortcode:
http://antartide.mondointasca.it/video-prova-youtube-video/
And the plugin is activated as you can see on this screenshot:

No. As mentioned earlier, you’ve installed another YouTube plugin — the very plugin that we said to uninstall is the one shown in your screenshot. Keep in mind that just because a plugin states it is a YouTube plugin doesn’t mean it is ours.
Our plugin is on version 11 and the one you have there has a much lower version number. It also doesn’t have our name on it. Please uninstall it and install ours in order to have the shortcodes work.
Perhaps you’d like the direct download link so you get the right plugin (ours) file: https://downloads.wp.xz.cn/plugin/youtube-embed-plus.11.0.zip
Good luck,
