Facebook sharing: “href should represent a valid URL”

Could you please provide a screenshot of the error you’re getting? It doesn’t look like it is caused by the Yoast SEO plugin. Upon further inspection of the URL, it looks like it is using a relative link instead of an absolute link.

Generally speaking, an absolute link defines the location of the document in total including the protocol ( e.g., “http://” or “https://” ) required to get the document. Whereas, a relative link is any URL that doesn’t explicitly specify the protocol.

This might be related to your CDN or some other plugin that is causing the output of the relative link. If you change it to the absolute link, it should resolve the issue.

As much as we’d love to help, our plugin does not output share buttons and, therefore, this support forum is not the best place to request assistance.

That being said, we do see that your site is removing the http/https protocol from multiple parts of your website code. This is typically done either with a post HTML modification (typically by your webhost) or through a plugin that resolves mixed content warnings. If you’re unsure what part of your setup is causing the issue, we recommend a conflict check.
