How to change the title of custom posts?

Question

WordPress

Hello. For all pages on the site, the title looks like this: Page title | Name of the site. There is a custom post type - portfolio and a page with the same address. There is an archive-portfolio.php page. But on such pages the title looks like this: Page Title - Site Title. Those. through dash. Can this be fixed somehow?

Answer 1

So no one suggested it. Decided to change the default separator.

add_filter( 'document_title_separator', function( $sep ) {
    return '|';
} );

This is solved with two lines of code in functions.php, read vp-kama and you will have chocolate!
