Ok, i found it! 🙂

It was error in function made for limited excerpt by character:

function get_excerpt(){
$excerpt = get_the_content();
$excerpt = preg_replace(" ([.*?])",'',$excerpt);
$excerpt = strip_shortcodes($excerpt);
$excerpt = strip_tags($excerpt);
$excerpt = substr($excerpt, 0, 100);
$excerpt = substr($excerpt, 0, strripos($excerpt, " "));
$excerpt = trim(preg_replace( '/\s+/', ' ', $excerpt));
$excerpt = $excerpt.'...';
return $excerpt;
}

There was missing “\” in “/\s+/” 🙂

Thank everyone for help.

Letter “s” is missing only in excerpts, in title it is ok, for example first post (missing “s” is putted in [s]):

Title: “Centralne instalacje filtrowentylacyjne dla stanowisk spawalniczych”
Excerpt: “Projektujemy, wykonujemy a na[s]tępnie do[s]tarczamy i montujemy wielo[s]tanowi[s]kowe in[s]talacje…”
