Breadcrumb issue data-vocabulary.org wordpress

Hello,

we have received several (891) problems regarding the well known problem concerning the breadcrumbs in connection with data-vocabulary.org.

I’ve found out where this line is – it is here: wp-content/plugins/wordpress-seo-premium/frontend/class-breadcrumbs.php

The lines are:
` /**
* Wrap a complete breadcrumb string in a Breadcrumb RDFA wrapper.
*/
private function wrap_breadcrumb() {
if ( is_string( $this->output ) && $this->output !== ” ) {
$output = ‘<‘ . $this->wrapper . $this->get_output_id() . $this->get_output_class() . ‘ xmlns:v=”http://rdf.data-vocabulary.org/#”>&#8217; . $this->output . ‘</’ . $this->wrapper . ‘>’;

/**
* Filter: ‘wpseo_breadcrumb_output’ – Allow changing the HTML output of the Yoast SEO breadcrumbs class.
*
* @api string $unsigned HTML output.
*/
$output = apply_filters( ‘wpseo_breadcrumb_output’, $output );

if ( WPSEO_Options::get( ‘breadcrumbs-prefix’ ) !== ” ) {
$output = “\t” . WPSEO_Options::get( ‘breadcrumbs-prefix’ ) . “\n” . $output;
}

$this->output = $output;
}

Can you please help me with that? How can I update this?
