Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Please head over to Rank math > Dashboard and ensure you are switched to advanced mode( you will see it on you top right corner), then head to Rank math > General settings > Bread crumbs and Check if you have Breadcrumbs enabled. If they are enabled, make sure you have added the code provided under on the breadcrumbs setting page to the pages/posts you need breadcrumbs to appear.
It is however not recommended to have breadcrumbs on the homepage since they don’t provide any benefit there and can cause these errors.
Looking forward to helping you. Thank you.
