I registered a new domain and thought I make it more secure. Thus I tried to install a certificate. I even bought one. And they sent me the invoice with some number. But I do not see where that certificate is. It should be a .pem or .crt file. I search engined a bit and found a plesk forum (https://talk.plesk.com/) where somebody said, that she is witing now for ages for her certificate. I might be having the same issue….
