GSC error: data-vocabulary.org schema deprecated

[Lorel]

This is an error that showed up in GSC this morning:

data-vocabulary.org schema deprecated

An explanation can be found on Barry Schwartz's website for today's date.

The error in GSC indicates this is on a blog post. However I checked the code on that page and itemscope is nowhere on the page. And I have no plugins for Schema, (only OG). I have Yoast SEO installed.

Can someone tell me how to find what is causing the error?

i haven't seen this specifically mentioned as a common GSC glitch but GSC data glitches are common.

in case you weren't aware, there's a related thread here:

Search on Google shows that there are a fair number of discussions about this. I'm not a WP developer, but the problem seems to have to do with breadcrumbs and the type of schema output the breadcrumb generator outputs... and from there whether it's a theme or a plug-in.

In the WebmasterWorld discussion that phranque linked to ^^^, there is a mention of breadcrumbs, but it doesn't go further.

Best discussion on the problem I've found via quick searching is this one in the WordPress forum....

GOOGLE ERROR data-vocabulary.org schema deprecated

From your site’s source code, I see that your theme outputs breadcrumbs using the data-vocabulary.org schema. I, also, checked your theme’s demo and confirmed that their demo includes data-vocabulary.org schema. Please contact your theme author for assistance removing the schema.

Yoast says on several threads it's not them, because they use schema.org, and don't use data-vocabulary.org schema at all.

So, if you've got breadcrumbs, that's probably it. PLEASE report back here if that's the problem. Barry's article does have a sample of schema.org code vs data-vocabulary.org code. His article is at...

@Robert

Thanks. If it's not Yoast then I assume it's the Theme that needs to update.

That link to Barry's article shows you what to look for in your source code so you can see just what to look for. If you see similar code, yes, you should contact the Theme's creator to get a fix.
