A few weeks ago I received a message from the Google Search console tellling me that I had errors in the forum breadcrumb, that "name" or "item.name" shuld be specified

Anyone got the same issue? Is there a way to fix it?

hmmmm....we haven't seen anyone else report this issue nor are we familiar with the error.  Which simple:press theme are you using and do all of your breadcrumb links go to real pages?

It's a child reboot

for example, in https://www.subnoise.es/foro/v.....one-hides/

you can see:

  { "@context": "http://schema.org", "@type": "BreadcrumbList", "itemListElement": [ { "@type": "ListItem", "position": 1, "item": { "@id": "https://www.subnoise.es", "name": "Home" } }, { "@type": "ListItem", "position": 2, "item": { "@id": "https://www.subnoise.es/foro/", "name": "", "image": "https://www.subnoise.es/wp-content/uploads/2014/06/SN.png" } } ] }

Hi:

But do the breadcrumb links go where they should go?  I.e.: do any of them issue an error of any kind when you click on them?  We're not familiar with the intricacies of Google Search Console so the best advice we can offer on this is check whether or not the links actually end up where they should...

Yes, they work. I guess what's missing it's a name (or description) missing

I don't know what that could be - is it issuing the complaint for every single breadcrumb link for every single post?  Or just some of them?

Looks like it's the second link, but I don't see a third. Maybe it's a a WP issue 

Does SP generate this kind of schemas?

The first link is the link to your home page.  The second link is the link to your forum page.  (At the top of this topic you can see that's the same for this page too).  None of the links have any extra information attached to them in the html - they're all plain html anchor tags...

We don't generate any special schemas for the Google search console.  But we do generate a site map if the yoast seo plugin is installed.
