Works like a charm. Thanks.

Yup, but i need to activate plugin on network administroation dashboard, is that right way to do complete backup?

Hi. I solved my problem. functions.php file must be encoded in ANSI, not utf-8 as mine. When i changed encoding, everything works fine. Hope this helps someone.

Ok, i paste it here.

<?php

add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style' );
function enqueue_parent_theme_style() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
?>

Thats all that my functions.php file contains. Admin site won’t load neither with that file or blank file.

I do the job by adding js script on the footer that add some css classes to theme objects. Hope this helps if anybody have similar problem. Also it would be nice to hear if someone has better solution
