Twitter Cards are not whitelisted for my subdomains, work OK for root domain


Hi there !

I have twitter cards correctly whitelisted for my domain “”. I supposedly applied to “*”

However, if I type a subdomain like the card is not shown, and the validator says I have to apply for *

I think this worked in the past, but I’m not sure.

Can I apply for all subdomains at once? My site grants a subdomain to each user, a-la-tumblr, and I’d like to have all subdomains with working twitter cards!

Thanks in advance.
