 * When I try the Twitter validator, I get an “invalid card type” and can’t figure
   out what to change to fix this.
 * One of the URLs I’ve tried out is:

 * Hi,
 * You can start with :
 *     ```
       User-agent: Twitterbot
           Disallow:
       ```
   
 * in a file called `robots.txt` which should be located in the root of your website.
   Just tell me if this is working again.

 * Apologies, I thought I had that covered already. Now sorted and error message
   banished. Thank you.
