one site lets encrypt comes up other nothing.

&letsencrypt=1#letsencrypt has always worked when I went to security and ssl, then added this. On my mensvintageclothes.com site it was a button sending me over. On antiquetextilemuseum.com absolutely nothing. I add &letsencrypt=1#letsencrypt and refresh the page and nothing. I was told there’s a letsencrypt plugin but nothing comes up. So really what gives? The developer sent me a screen shot where he,has the headers: dashboard, settings, let’s encrypt. I don’t have let’sencrypt. If I did I probably would need to write this. How do I correct this so my website will be up to date again? Thank you.
