Well, I know I'm sort of solving this problem as I go along but here is my "solution" to the problem in Post #9.

In AuthPlugin_vBSSO.php, I added a chdir commands before the call to global.php:

define('THIS_SCRIPT', 'wiki');
chdir ('/home/puritanb/public_html');
require_once( CWD . '/global.php');
chdir ('/home/puritanb/public_html/includes');
require_once( CWD . '/includes/functions.php');
chdir ('/home/puritanb/public_html/w/includes');

It eliminates the error that it cannot find the functions_dfha.php file but I still cannot edit any pages or save preferences. I get this error when I attempt to edit pages:

Your edit has been rejected because your client mangled the punctuation characters in the edit token. The edit has been rejected to prevent corruption of the page text. This sometimes happens when you are using a buggy web-based anonymous proxy service.

I've tried clearing the cache and cookies and multiple browsers but the problem persists. I hope you're able to understand what the problem might be because I'm hoping to get this nice mod working. I'm even willing to contribute to this mod to keep it supported.
