Question

Search Engine Optimization

If someone has the same problem - check in header.php output Title? in my case it was

<title><?php bloginfo('name'); ?><? wp_title(':'); ?></title>

- I replaced it with <title><?php wp_title("", true); ?></title>(although wp_title is outdated for current versions)

Answer 1

Alternatively, remove the entire line from header.php
Then in function.php add title generation support:

function setup_theme() {
  add_theme_support( 'title-tag' );
}
add_action( 'after_setup_theme', 'setup_theme' );

Then, through the hook in the same place, in function.php, we remove the title from the internal pages:

add_filter( 'document_title_parts', 'mytheme_remove_title' );
function mytheme_remove_title( $title ){
  if ( !is_home() ) {
    $title['site'] = '';
  }
  return $title;
}

This is how it would be more correct.
