Exactly the same issue as @ginatrapani highlighted here: Summary Large Image Card displaying incorrect data
Our client posts links to their content, such as http://www.contiki.com/six-two/these-three-little-letters-could-change-your-life/. The metadata returned is entirely different, although when clicked on it goes to the correct URL. See this tweet.
I have gone through the cards troubleshooting FAQ. I’ve checked the metadata; we are running WordPress, and have had Yoast SEO’s support team confirm the metadata is correct. We have checked robots files for origin servers, CDNs, etc. Twitterbot’s new IP ranges have been whitelisted with WP Engine and with CDNs.
The validator is returning either a redirect error or - often with the same URL - returning as “correct” but showing incorrect metadata, as with the above linked tweet. I have CURL’d, including as Twitterbot, various URLs from various locations around the world; we get 200 OK with no redirects involved and grep showing twitter metadata is present and correct.
I am at a loss as to why this is happening, and would appreciate some support.
