Thanks for getting back to me James.  Previously, when someone gave me
some advice I would spend a great many hours troubleshooting further
when their suggestions didn't pan out.  To be honest, my failure to get
RT running has been very humbling so if I follow someone's instructions
and they don't solve the problem (or make things worse) I just respond
with the results and hope for more guidance.

I cannot fix this problem on my own.  I feel extremely stupid because of
this.  I'm an idiot.  I cannot do this without some help.  'Nuff said?

I removed all of the other Web stuff as you instructed.  No difference.

Error log follows.

I don't know how to answer your mod_fastcgi question except to say that
I followed the installation instructions religiously, that I have no
clue what fastcgi is and that below I have included two examples...  the
first, which is based on your suggestions, which does not work.  The
second, following the installation procedure instructions, which does
work but as I said, using the root URL.  As you can see, the
configurations are nearly identical.  Imagine my frustration, if you
can, that I have spent around ten days [unsuccessfully] troubleshooting
a problem that I isolated to two or three lines of code a week ago.  I
have nearly 45 years of computer systems engineering experience and at
one time I actually was smart.

Mail from SKYNETWEBBLACKHOLES is blacklisted on our mail server due to
them hosting spammer sites I presume.  I added both of your e-mail
addresses to my whitelist.  It's probably best to keep this thread
intact on the forum though.  The first thing I did, before asking anyone
for help, was to search the database for similar threads and found
nothing helpful.  Hopefully, if/when this gets solved, I will put a
clean configuration update for those who follow to use as a model.

RT is most likely [temporarily] accessible from the Internet.  If so,
you can see that http://backup.easyrider.com brings up RT nicely.  All
attempts to run RT from http://backup.easyrider.com/helpdesk have so far
failed.
