Replace “Blog – Aktuelle Neuigkeiten” with …

I use show Breadcrum and Title. And i want to replace “Blog – Aktuelle Neuigkeiten” with the name of the actual post?

i have always this code in the child theme function and can change the html code.

if( ! function_exists( ‘avia_title’ ) )
{
/**
* advanced title + breadcrumb function
*

{
global $avia_config;

if( ! $id )
{
$id = avia_get_the_id();
}

$header_settings = avia_header_setting();

if( $header_settings[‘header_title_bar’] == ‘hidden_title_bar’ )
{
return ”;
}

$defaults = array(
‘title’ => get_the_title( $id ),
‘subtitle’ => ”, //avia_post_meta($id, ‘subtitle’),
‘link’ => get_permalink( $id ),
‘html’ => “<div class='{class} ‘><div class=’container’>{heading_html}{additions}</div></div>”,
‘heading_html’ => “<{heading} class=’main-title entry-title {heading_class}’>{title}</{heading}>”,
‘class’ => ‘stretch_full container_wrap ‘ . avia_is_dark_bg( ”, true ),
‘breadcrumb’ => true,
‘additions’ => ”,
‘heading’ => ‘h1’, //headings are set based on this article: http://yoast.com/blog-headings-structure/
‘heading_class’ => ”
);

if( is_tax() || is_category() || is_tag() )
{
global $wp_query;

$term = $wp_query->get_queried_object();
$defaults[‘link’] = get_term_link( $term );
}
else if( is_archive() )
{
$defaults[‘link’] = ”;
}

// Parse incomming $args into an array and merge it with $defaults
$args = wp_parse_args( $args, $defaults );

/**

* @since < 4.0
* @return array
*/
$args = apply_filters( ‘avf_title_args’, $args, $id );

//disable breadcrumb if requested
if( $header_settings[‘header_title_bar’] == ‘title_bar’ )
{
$args[‘breadcrumb’] = false;
}

//disable title if requested
if( $header_settings[‘header_title_bar’] == ‘breadcrumbs_only’ )
{
$args[‘title’] = ”;
}

// OPTIONAL: Declare each item in $args as its own variable i.e. $type, $before.
extract( $args, EXTR_SKIP );

if( empty( $title ) )
{

}

}

if( ! empty( $subtitle ) )

}

if( $breadcrumb )
{

}

if( ! $title )
{
