Twitter card: Not Whitelisted


Hi there

I thought whitelisting wasn’t implemented anymore by reading the latest posts. We have been getting this error:
* is not whitelisted for … with the following log:
INFO: Page fetched successfully
INFO: 18 metatags were found
INFO: twitter:card = tag found
WARN: Not whitelisted

Is this a problem with the code or can twitter staff whitelist or website url?
