Trying to add a Summary Card with a Large Image to my site. http://www.apolloriyadh.com but whenever I try to validate my card this pops up in the error log:
INFO: Page fetched successfully
INFO: 14 metatags were found
WARN: Not whitelisted
I’ve tried to do it on both my site and this post: http://www.apolloriyadh.com/single-post/2016/08/25/Behind-the-Scenes-of-Beyonces-Lemonade
Both receive the same message in the log.
