Hello,
To remove the archive, you have to add the custom code in your child theme functions.php file.
To know how you can create and activate the child theme refer to below given link:
https://wptravel.io/how-to-create-a-child-theme/
Now after the activation of the child theme, add below given code in your child theme functions.php file.
function realestate_child_remove_cat_titles($title) {
if ( is_archive() ) {
$title = single_cat_title( '', false );
} elseif ( is_tag() ) {
$title = single_tag_title( '', false );
} elseif ( is_author() ) {
$title = '<span class="vcard">' . get_the_author() . '</span>' ;
}
return $title;
}
add_filter( 'get_the_archive_title', 'realestate_child_remove_cat_titles' );
Hope this helps.
Thank you.
