Site is Missing

Hi,
I’m using wp3,6 and the theme graphene. I didn´t access my site for a while, and today when I tried to login, I saw only a white screen. After renaming the plugin folder to see if the problem was there, I saw a message that says:

Notice: get_current_theme is deprecated since version 3.4! Use wp_get_theme() instead. in /home/jenfeibe/public_html/wp-includes/functions.php on line 2919

Notice: wp_register_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in /home/jenfeibe/public_html/wp-includes/functions.php on line 3060

Line 2919 says ‘trigger_error( sprintf( __(‘%1$s is deprecated since version %2$s! Use %3$s instead.’), $function, $version, $replacement ) );’

Line 3060 syas ‘trigger_error( sprintf( __( ‘%1$s was called incorrectly. %2$s %3$s’ ), $function, $message, $version ) );’

Any suggestions?
