Site title and description shows twics

caused by the filter function on ‘wp_title’ in functions.php of the theme.

to remove that filter, add this in a child theme of academica, in functions.php:

add_action( 'after_setup_theme', 'aca_child_setup', 11 );
function aca_child_setup() {
	remove_filter( 'wp_title', 'academica_wp_title', 10, 2 );
}

then possibly use a seo plugin for the meta titles.

That worked, thanks. However, I went to my website and looked at the source code, and I didn’t even see any meta titles for search engines. Am I not looking correctly?

in the html code in the browser, the meta title comes a bit lower as it is added via the ‘wp_head’ action hook.

in the php code, the meta titles are added via a add_theme_support() code in functions.php;

// Title Tag
	add_theme_support( 'title-tag' );

and then filtered via:

/**
 * Creates a nicely formatted and more specific title element text
 * for output in head of document, based on current view.
 *
 * @param string $title Default title text for current view.
 * @param string $sep Optional separator.
 * @return string Filtered title.
 */
function academica_wp_title( $title, $sep ) {

	if ( is_feed() )
		return $title;

	global $paged, $page;

	// Add the site name.
	$title .= get_bloginfo( 'name' );

	// Add the site description for the home/front page.
	$site_description = get_bloginfo( 'description', 'display' );
	if ( $site_description && ( is_home() || is_front_page() ) )
		$title .= " $sep $site_description";

	// Add a page number if necessary.
	if ( $paged >= 2 || $page >= 2 )
		$title .= " $sep " . sprintf( __( 'Page %s', 'academica' ), max( $paged, $page ) );

	return $title;
}
add_filter( 'wp_title', 'academica_wp_title', 10, 2 );

this line in the filter function was causing the problem because the dot before the equal sign was appending the original meta title content before the new build one:

$title .= get_bloginfo( 'name' );
