[SOLVED!] Installation Issues, 500 Internal Server Error

I started out writing Assembly utility routines for an Amstraad 8086. I think the highlight of my "career" was the chance to play with an old AS/400 that the University medical center I was working for was phasing out in favor of a Novell network of Windows PCs. (no need to recount all the disasters, like the time 2 years worth of doctor’s dicatations were lost, and only six months worth of backups could be found...). The hardware was in cabinets the size of three small refrigerators. It had a built-in tutorial system for learning OS/400. It was wonderful. Because of that experience, I almost got a job with a large Miami freight company that was having IBM install a new AS/400 system, and I was going to attend the installation and be tutored by the installers. Less than a week before the installation and my hiring, one of their planes crashed just outside the airport on takeoff - poorly unsecured bales of old clothes shifted. The four crew members and one civilian in a car on the ground were killed. So... here I am, in Israel, fiddling around part-time with HTML and PHP instead.
