Unable to render Card preview

[PCGambler]

Hi guys,

I am trying to use the card validator (https://cards-dev.twitter.com/validator) with my website:
http://procomputergambler.net/

I am getting the error: "Unable to render Card preview"
and also

Any ideas?

Can you list the specific twitter:card markup you believe is present on that page? I cannot find any.

twitter:card

Hmm. Not sure. I am using the squirrly seo plugin and activated twitter cards in there.
I am on a wordpress platform.

OK, unfortunately we don’t directly support that plugin as our own code, and as I explained I’m afraid when I load your site, I see no twitter:card markup, so I’m not sure how to help you. We have our own Wordpress plugin if you prefer.

Hi Andy

I’m getting this same issue on eg. http://blog.vwriter.com/repurpose-your-blog-post-as-a-quality-youtube-video/

Get the same ‘Unable to render Card preview’ output, along with

WARN: Not whitelisted

The correct tags are all showing in the source, would appreciate any advice?

Thanks
Steve

I’m getting a blank page when I try to fetch that using my browser or when using curl.

That fixed it, thanks - blog was showing fine to me as I was logged into it, but not otherwise, recent plugin issue it seems. Thanks!
