So fortunately I was able to get the Power CMS fully working again just in time for my meeting (thankfully)
this fix posted in earlier forum worked:
require_once( "../WA_SecurityAssist/Helper_PHP.php" );
//require_once( "../WA_SecurityAssist/Helper_PHP.php" );
however, I am still having trouble on the login page getting it to redirect.
I am unsure how the WA_CMS page was changed, I think Ray posted a new one for me...would this have been changed in the posting of the SecurityAssist Authenticate Users behavior? If so, I am unsure how I am suppose to do any updates with the Security Assist without screwing up the PowerCMS...I appreciate your help in trying to figure this issue out and working out the login page problem.
