Wordpress - change post title in page header

Question

At this link: http://wp.ubiqui.com.br/2017/05/24/central-de-marketplaces/ you will see that on the image is the post title.
I would like to put a code in Wordpress so that, only when accessing a post, it changes to "News".
On the other pages, it’s to stay the way it is.

Answer 1

You can use the "wp_title" filter. In your functions.php file you can insert something like:

function trocar_titulo($title){
    if(is_single()){
        return "Notícias";
    }
    return $title;
}
add_filter( 'wp_title', 'trocar_titulo', 10, 2 );
