Customize Page Title in Breadcrumbs

Hey Celeranttechnologycorp,
First ensure that the Custom Fields option is enabled in the Screen Options at the top of your page in the Classic Editor:

Or in the Block Editor, go to Preferences ▸ Panels ▸ Custom Fields:

Then add a custom field custom_title and enter the value you want:

Then add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

add_filter( 'the_title', 'custom_field_title', 10, 2 );
function custom_field_title( $title, $post_id )
{
    if( $new_title = get_post_meta( $post_id, 'custom_title', true ) )
    {
        return $new_title;
    }
    return $title;
}

and your custom title will show in the title bar:

Best regards,
Mike
