Hi,
If your theme is using the standard WooCommerce breadcrumbs, then they don’t provide a way to make the last breadcrumb clickable, which also means that my plugin can’t do that either.
With that said, it really doesn’t make sense to make it clickable anyway, as the last breadcrumb simply shows the name of the current page that you’re on. If it was clickable, it would only link back to itself.
As an example, take a look at this screenshot of a WooCommerce product page:
https://share.getcloudapp.com/04u2XwD0
The last breadcrumb in the example above is “Canon EOS Rebel SL2 Kit” which displays on the Single Product page for that particular product. If that was a clickable link, it would simply link back to the exact same page that you’re currently viewing, which doesn’t provide any useful functionality.
I hope that helps.
