Summary with large image: "Unable to render" despite meta tags found


Hi support,

I’ve implemented all the required meta tags for a “summary_with_large_image” card, but I cannot make it work.

The meta tags are properly displayed in the source, even when crawled by the “Twitterbot”.

Here is the validator result:
INFO: Page fetched successfully INFO: 20 metatags were found INFO: twitter:card = summary_card_with_large_image tag found WARN: Not whitelisted
The URL of the page is:

I followed the Not Whitelisted, unable to render, or no image: What To Do Next guide, but everything seems to be ok.

Could you please let me know if something is wrong on our end ?

Best regards


This is not a valid value - the correct value you want is summary_large_image
