I already solved the problem. I added this to wp-config.php:
define(‘ALLOW_UNFILTERED_UPLOADS’, true);
It allowed to upload forbidden files.
P.S.- You can delete it after all for more security.

Sorry for delay. Everything well, thanks! ??

Nothing happens in whole dashboard page :). Any click on any place on dashboard doesn’t work. (other pages and left menu work well)

Great job! Works perfect on 4.5!
