From what I understand our dev team are following the standards and I'm not an expert on what is included in those.
Also please read the following:
The only reason for a button to suddenly stop working and having this error is if you have changed a setting on your site that would provide us with a different URL to the one that was there when the very first button was rendered.
If it is something that changed recently and required us to re-crawl your site then the ping service would have updated that on our end. Since you say that you've already run that, this would suggest that your site is showing one URL but actually pointing to a different one.
Unfortunately we don't have the ability to fix your site, that is something you would need to look into as only you know what you have changed between the two posts. In all likelihood there will be a plugin not functioning as it should do or a canonical link that has been misconfigured.
Many thanks
