Tests the renewal!
===PDFEmbed Issus==
Enabling and requiring HTTPS causes an issue with PDFEmbed on mediawiki, where you get a blank frame. The PDF is still there, other images load fine, but the PDF frame won't render the PDF. The problem is actually that the PDF is served with HTTP and the rest of the page is served with HTTPS, and Chrome (and perhaps other browsers) don't render the insecure content as a consequence (see [https://www.mediawiki.org/wiki/Topic:Uhgnq0wbmzfurbj0] for a description of the symptoms, but not the solution.).
The solution is to edit mediawiki/extensions/PDFEmbed/PDFEmbed.hooks.php. For me it was line 103 that previously said:
'src' => $file->getFullUrl().'#page='.$page,
I changed this line to:
'src' => preg_replace("/^http:/i", "https:", $file->getFullUrl()).'#page='.$page,
This is mentioned in a comment on a topic page, though presumably for an earlier version: https://www.mediawiki.org/wiki/Topic:Syxow0why4c0cvvm
