Hi- If you search tech gardens, you'll see this in place of the meta description. I had the same issue before: https://www.experts-exchange.com/questions/28972532/A-description-for-this-result-is-not-available-because-of-this-site's-robots-txt.html
This time, the robots.txt file reads:
I've gone to Google and asked it to fetch as Google, but I'm not sure that's all I need to do. Could you advise me, please and thanks?
Site is techgardens.com, wordpress latest release, Divi theme.
