Hi @matwp,
Thanks for your patience. It’s very strange to hear that the breadcrumbs are working on other pages and not your blog posts. If you didn’t find any conflicts or errors, we think the issue is something specific to your site.
We would need to investigate further by looking at your specific site but we’re not able to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.`
If you’re able to find the source of the conflict or if you can give us the steps to reproduce this problem on a test site, we ask you to create a new bug report for our developers. You’ll need a GitHub account to create a new issue.
If this is your first bug report, please check out:?How to write a good bug report.
We’re sorry that we haven’t found a solution, but we’re happy to investigate further.
