Breadcrumb issue

Hey swisstraveler,

Thank you for the inquiry.

Would you mind providing a screenshot of the issue? We found no breadcrumb element in the site, so the error should not be occurring in the console. Did you try to run the validation process?

Hi,

Looks like the breadcrumb is generated using the function generate_breadcrumbs but we are not yet sure how the context is generated. We might be able to filter the value of the context before passing it to the breadcrumb schema generator.

plugins\wordpress-seo\src\presentations\indexable-presentation.php > line 664

	/**
	 * Generates the breadcrumbs for the page.
	 *
	 * @return array The breadcrumbs.
	 *
	 * @codeCoverageIgnore Wrapper method.
	 */
	public function generate_breadcrumbs() {
		return $this->breadcrumbs_generator->generate( $this->context );
	}

Best regards,
Ismael

Hi,

Do I get it right that you can now provide a filter

No, the code above is the function that generates the breadcrumb schema. We cannot find any filter, or we are not sure how Yoast generates the context. Have you tried selecting a page as blog as they recommended above?

Hi,

Thank you for the inquiry.

Try to select the current home page as homepage in the Settings > Reading panel, and create another page and set it as posts page.

We tested the link with each parameter and found that the m=0 parameter causes the incomplete breadcrumb schema.

The query var avia-element-paging=25 is created by the theme for the pagination, but we have no idea where m=0 is coming from. It might be from another plugin. And according to Yoast this variable is causing the issue.

Hi,

To resolve the issue, you have two options:
Create and select a page to be treated as the blog page
Add custom code to remove the breadcrumb schema from the source code when the blog page is referenced. An example of how to do this can be found here.

Did you follow any of these recommendations? According to them, the issue is caused by not having a static blog page, which creates the m=0 parameter.

Did you try to set a static blog page? You can assign a different page as blog page and it should not affect the posts that displays in your home page, which seems to be what you are concern about. You can always revert it back to the previous settings if the results of the changes are not what you are expecting.

An example of how to do this can be found here.

Would you mind providing the actual link?

Hi,

Alright. You can also add the filter that they provided in the link to remove the breadcrumb entry from the schema.

/********* DO NOT COPY THE PARTS ABOVE THIS LINE *********/

/* Remove Yoast breadcrumb from static blog page

add_filter( 'wpseo_schema_webpage', 'remove_breadcrumb_schema_ref', 10, 1);
function remove_breadcrumb_schema_ref( $piece ){
	if ( !is_front_page() && is_home() ) {
		unset( $piece['breadcrumb'] );
		return $piece;
	}
	else return $piece;
}

add_filter( 'wpseo_schema_graph_pieces', 'remove_breadcrumbs_from_schema', 11, 2 );
function remove_breadcrumbs_from_schema( $pieces, $context ) {
	if ( !is_front_page() && is_home() ) {
		return \array_filter( $pieces, function( $piece ) {
			return ! $piece instanceof \Yoast\WP\SEO\Generators\Schema\Breadcrumb;
		} );
	}
	else return $pieces;
}

Please feel free to open another thread if this continues to be an issue. We will close this one for now.

Have a nice day.

Best regards,
