Summary Large Image Card Not Working



I keep getting this message every time I try to implement the meta tags to my site, I was hoping someone could help

INFO: Page fetched successfully
INFO: 8 metatags were found
WARN: Not whitelisted


There’s a good debugging guide in the pinned topic. It looks like you’re trying to add the twitter:card tag via Javascript, but that will not work using our crawler, and it is also not working in a browser. Ensure that the correct tags appear when fetched manually using the Twitterbot user-agent.
