I am trying to set up Twitter cards on new pages on our website. It worked to start with but now I am getting a warning we are not whitelisted, but I did get us whitelisted a few weeks ago.
For example I tried to set up a Twitter card for this page:
and got the following warning in the Twitter card validator:
INFO: Page fetched successfully
INFO: 14 metatags were found
WARN: Not whitelisted
Any help very much appreciated!
