I recently received those error reports from Google as described here:
I’m using the Yoast breadcrumbs in Customizer settings for displaying in my pages, and that works fine, but I don’t know what the problem is with Google.
It seems these are errors from the theme:
– Invalid URL in field “id” (62 errors)
– Either “name” or “item.name” should be specified (2 errors)
– Missing field “item” ( 2 errors)
Are you planning to update the theme accordingly?
