I hope someone can help me resolve my issue, everything use to work perfect then all of a sudden no cards displaying on twitter from my shares to my twitter, all other social media works great just twitter cards i get nothing apart from title and link.
I have tried and tried with the card validator, but the error i keep getting no matter what i try is:
“ERROR: Fetching the page failed because the fetcher cannot resolve the address.”
i have changed my robots.txt file to allow Twitterbot but still nothing.
