The breadcrumbs plugin included during install hasn’t been updated in three years and it throws an “Invalid URL in field id” error in Search Console, negatively impacting rich snippets. Can you recommend an alternative?
Thank you for reporting this issue, I have passed the request to our developers regarding this matter. Meanwhile, you may try using some alternative plugins, e.g.: Breadcrumb NavXT. Please note that you may need to perform additional steps in order to integrate it to the theme and we do not guarantee its full compatibility with the Campterra theme, as it was never tested with it.
