Primary category for breadcrumbs ignored

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

I have checked your site https://beautycrushskin.com.au/mugwort-mask-110g/ and it seems that the breadcrumbs are being displayed by the WooCommerce plugin.

“Primary category” functionality is offered by the Rank Math plugin. WooCommerce does not have this option by default and if you want to display “Primary category” in the breadcrumb, I suggest you use the Rank Math’s Breadcrumb functionality.

You can activate the breadcrumbs setting in Rank Math from Rank Math > General Settings > Breadcrumbs.

Then add the Rank Math’s breadcrumbs code to your theme’s template files, and the breadcrumbs will appear on your website’s front-end accordingly.

/**
 * Use the following code in your theme template files to display breadcrumbs:
 */
<?php if (function_exists('rank_math_the_breadcrumbs')) rank_math_the_breadcrumbs(); ?>

Paste the above code directly into your theme’s single.php or header.php wherever you prefer showing it.

Here is a guide that might help you:

You can also use this code snippet in your theme’s functions.php file to remove Woocommerce breadcrumbs from all pages:

function remove_wc_breadcrumbs() {
remove_action( 'woocommerce_before_main_content', 'woocommerce_breadcrumb', 20, 0 );
}
add_action( 'init', 'remove_wc_breadcrumbs' );

Hope this helps.

Looking forward to helping you. Thank you.
