I noticed on an Ubuntu 18.04 LTS server I have running Virtualmin Pro: when I went to Server Configuarion -> SSL Certificate I was confronted with a Perl error. I was already in the process of spinning up a 20.04 LTS server (also with Virtualmin Pro), so upon completion, I checked it there too. After adding a site and checking " Apache SSL website enabled?" I was confronted with the following error; (Additionally when I tried requesting a new Let'sEncrypt cert, or updating a cert in general, it said it was successful, but no change certs were still self-signed). The error is:
HTTP/1.0 500 Perl execution failed Server: MiniServ/1.954 Date: Mon, 24 Aug 2020 06:52:46 GMT Content-type: text/html; Charset=utf-8 Connection: close Error - Perl execution failed Modification of non-creatable array value attempted, subscript -1 at /usr/share/webmin/virtual-server/feature-ssl.pl line 919.
*** I checked all of my servers with Virtualmin, and all suffer the same issue, I looked for hours, but this doesn't seem to have been reported ***
