We applied and got an approval for a Twitter Card for our domain “whisp.to” over a year ago. It was rendering properly until Feb '15. The reason was a security hole that’s detected in our player card and actually we reported back to Twitter Support after fully fixing it. Since the mentioned date our player card is not being displayed on Twitter timelines. I checked the log from validator and it shows me the popular warning “WARN: Not whitelisted” (please find attached screenshot). May anyone there please fix this issue?
Player card that was approved a year ago now doesn't appear on timelines and validator log shows "WARN: Not whitelisted"
at least you would have login and upgrade once in a year to avoid over sleeping
Actually it’s problemeatic for almost 5 months now and I already contacted Twitter Support before, still no change.
