I’ve added your code in the class constructor function of wordpress-seo/frontend/class-breadcrumbs.php. Below is the link to the validation for the page. Let me know your thoughts.

See the Results

Hmmm… it actually causes more errors than the 3 pre-existing ones (5 now). The issue is the itemtype, itemprop and itemscope not being recognized attributes. I haven’t checked your facebook fix but the breadcrumbs update you listed maybe needs a little more tweaks.

Hey Folks, it looks like thomask posted a few things to try for resolving certain validation issues.

Hey thomask, this is great that you’ve looked into this. Does the breadcrumb fix validate with the w3c validator?

Also, where would you insert the breadcrumb filter code?
Did you add it to a specific file from the plugin or your theme itself?

Thanks in advance,
