Hi everyone - I am struggling a bit to troubleshoot twitter cards on links to my forum and understand what to do to fix it. There are some interrelated features that I am no clear on how they play together. Any guidance much appreciated.
The card validator at https://cards-dev.twitter.com/validator indicates “ERROR: Fetching the page failed because it’s denied by robots.txt.” for topic URLs on my forum. But links to topics on meta work fine. I have twitter logins enabled, though I use SSO. I also have search engine indexing disabled.
