Unable to render Card preview


Good Morning,

That’s the first time that i try to using summary card in my site, i put all meta tags, edit the robots.txt to permit the Twitterbot to crawl the page, but i continue to have this error below:

Thanks, any advice could help a lot.


Check the value of the twitter:card tag. It should be one of the valid card types, not the string you have entered.


Thanks for the help andypiper, I had misunderstood the use of this tag.

Thank you :slight_smile:
