[Plugin: WordPress SEO by Yoast] Adding opengraph meta data makes header W3C Invalid

I do have also a problem with this meta-tag:

In the yoast-part in the header:
<meta property=”og:locale” content=”nl” />

Facebook debug tool error:
“Object at URL ‘https://www.dailybits.be/item/behind-the-scenes-your-bags-airport-journey-door-delta/&#8217; of type ‘article’ is invalid because the given value ‘nl’ for property ‘og:locale:locale’ could not be parsed as type ‘enum’.”

It should be “nl_BE” or “nl_NL” not?

I modified your code and hardcoded my “nl_NL” value where your are writing the local-tage and now everything is working, so could you bugfix this in your next version? thx!

How do I change the locale value as our source states:

<meta property='og:locale' content='en_us'/>

but we are not in the US?

indigoclothing: please make a new thread next time as your issue is not related. The plugin takes your locale from the wp-config file.

Okay, back to the issue at hand… the code still doesn’t validate.

<meta property=’og:locale’ content=’en_US’/> is the line that is reported with errors. I have a client that is demanding all errors be resolved, but without hacking the plugin, I can’t.

Can you suggest something?

They said this issue is resolved? It’s clearly not! Infact you guys have had plenty of time to work out the open graph bug. Why not?
