Este posibil să utilizezi add_filter dintr-o temă pentru a modifica o funcție a unui plugin?

Poate fi folosit add_filter() pentru a intercepta o funcție a unui plugin?

Nu am reușit până acum, așa că mă gândesc că poate fac ceva greșit.

Plugin-ul este "All in One SEO" iar funcția pe care încerc să o interceptez se află în clasa All_in_One_SEO_Pack și se numește get_original_title()

Iată codul pe care încerc să-l interceptez...mai exact, când este apelată metoda is_404()...

class All_in_One_SEO_Pack {

function rewrite_title($header) {
    global $aioseop_options;
    global $wp_query;
    if (!$wp_query) {
        $header .= "<!-- nu s-a găsit wp_query! -->\n";
        return $header; 
    }

    $post = $wp_query->get_queried_object();

    // the_search_query() nu este potrivit, nu poate doar să returneze
    global $s;

    global $STagging;
