I just set up the Twitter card option via Yoast in my WP website, http://invitadoinvierno.com/, and I get the message Unable to render card preview with this log:
INFO: Page fetched successfully
INFO: 6 metatags were found
ERROR: No card found (Card error)
I’ve checked the source code of the page and the tags seem to be there. I’ve also checked previous forum discussions on similar issues, but none seem to make things a few clearer for me.
I would really appreciate some insights on this. Thanks!
