AddHandler fcgid-script .html
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .html
I replaced it with this:
AddType application/x-httpd-php5 .php5 .php4 .php .php3 .php2 .phtml .htm .html
The Internal Server Error is no longer present and PHP functionality has returned to HTML files. It was my impression the first level technicians were not properly routing my call. It is unfortunate that GoDaddy does not appear to have an email contact form for Technical Support. Email is quite effective at documenting and sharing technical information. Without being properly routed to a GoDaddy Hosting Administrator, I am left to find a solution myself for what may have been a change made by GoDaddy staff to the Server hosting this website. I am certain that if a second-level technican in the GoDaddy Hosting Department had been assigned this ticket, they would very likely have been able to isolate the source of this problem and resolve the issue at GoDaddy. I think many customers would greatly benefit if GoDaddy re-evaluated their present routing of tech support calls.
