Hrohh

Ok, nevermind. Thank you.

It is possible import PO file to Glotpress? Because I do not have time to translate the extension twice. 🙂

Now I filter via this code and I think it is better way to do it.

add_filter('load_textdomain_mofile', 'custom_load_textdomain_mofile', 999, 2);
function custom_load_textdomain_mofile( $mofile, $domain){
    if ($domain == 'acf')
        $mofile = 'mypath/wordpress/wp-content/languages/plugins/acf-cs_CZ.mo';
    return $mofile;
}
