Can't access into ADMIN anyway

Are you sure your website is working correctly ? Loading the homepage took THIRTEEN seconds on the second try, and two more on the first try. Nobody in the world, unless clicking a link from a support forum, has the patience to believe the website is working.

As for your problem, the simplest thing would be to reinstall wordpress, are you familiar with FTP ? If so, you can simply grab the wordpress zip file from www.remarpro.com (or your localized version of course, if you want it in Italian), and overwrite the contents of your wordpress folder on your hosting space with the contents of this zip.

That alone has already high chances to fix your issue. And when you have it fixed, consider adding a caching plugin like wp-supercache, to make your site load faster ??

hi, thank you so much for your time.
I had tried to deactivate all plugins changing the name of plugins directory in plugins.deactivate.
Now web site seem performing well but still i can’t access my admin.
I receive nothing as response or a time-out error.

At least your website works super fast now, congrats ?? When things are fixed, if you want, there’s the P3 Plugin Profiler wordpress plugin, that tells which of the plugins is eating away lots of resources or taking a long time to load.

Regarding your problem, hmm, have you tried reinstalling wordpress ?
(As mentioned above) You don’t risk to lose anything, neither a theme nor a plugin or personalized data, options or files.

i’ll try to reinstall admin…
i hope to win!

Not just admin, if you were thinking of the /wp-admin/ folder in the wordpress zip archive. The wp-includes and wp-admin folders.

If your connexion is slow, you can FIRST upload those two folders to a temporary folder, like (blog root)/temporary/ , delete /wp-admin/ and /wp-includes/ , and then move the contents of /temporary/ one directory above.
See the idea ?

I’ll reassure you, if you only delete this, you risk to lose NOTHING, wordpress is well conceived and your own data lies in specific places : (root)/wp-config.php , (root)/.htaccess , (root)/wp-content/uploads , (root)/wp-content/themes and (root)/wp-content/plugins (those two last folders being for the most of them reinstallable from scratch in a few clicks, unless you created a child theme or stored variations in your theme’s functions.php)
As for the content of your posts, your options, your settings, everything inputted manually, this is stored in your database, that your web host stores in a place that you cannot access manually, it is read/written/backupped in a different manner.

So, the worst that can happen after reinstalling wordpress, is that your problem could still be unsolved.
