Issues after Wordpress update to 3.5

After Wordpress update to 3.5, LinuxId don't allow load media files in admin panel, switch between visual/html in posts editor, etc. I use clean Wordpress without ANY plugins, so plugins can't affect on this. After switch to standart theme, for instance TwentyTwelve, all works fine.
Thanks.
