When I try create a Twitter Card, it keeps coming up as "Not Whitelisted" on the Card Validator


I’m new to Twitter Cards, and thought I had done it all correctly. Trying to use Twitter Cards to showcase my blog on a tweet (just as a summary card), I’ve added the relative HTML into my blog, and when I try the card validator, it says the page has been fetched and 7 metatags have been found, but then it says Not Whitelisted.

Any help?


Are you able to share a link to a page with the meta tags included?


Hi Andy - thanks for getting back to me. I’ll let you know in a moment, checking the HTML source as a third party, I can’t seem to find the Meta tags stored in the page. When i’ve finished work i’ll have a play and see what’s going wrong with the html coding in the blog
