Parsing PHP in HTML broken

On my DH site I had it configured to allow parsing of PHP in HTML files so that I could embed <?php ... ?> into the HTML files and have it do the right thing.

I just noticed that recently (within probably the past month) this is no longer working. Not sure if it was a PHP update or what. Can anyone advise?

I have HTML Like this:

Photos from Saturday for our last High Performance Driving school of the season are posted in our gallery.

I have .htaccess that has:

AddHandler fastcgi-script fcg fcgi fpl
AddHandler php5-cgi .php .html
RewriteEngine On
RewriteRule .git - [F,L]
ErrorDocument 404 /error_document.html
SetEnv TZ America/New_York

THis work, I think as recent as 10/1/2016, but does not work now. No changes to site.
