Yep, I think I hosed the new install.

I imported the old Data.fs and corresponding .zexp files over and now it
won't let me into the localhost:8080/manage interface even.  I keep
getting connection refused messages there.

I have restarted zope.  Tried to restore the working Data.fs file...but
all is still not well. When I point to the Start Page that everyone
should see, I get the authentication window and it does authenticate,
but then I get "Bad Gateway
The proxy server received an invalid response from an upstream server."

Do I have to start all over?  Which is ok and maybe more efficient in
getting this project off my plate (rather then peck my way through code
I have no understanding of, (python).  Unless you know what I can do to
fix it quickly.  

Is there a way to cleanly uninstall Zope if I have to go this route?  I
compiled from the tar.gz and didn't use an RPM.

Then what I want to do is start all over and set up a knowledge base:

On an RHEL4 box:
A fresh install of Zope (2.8.0 now) with; an apache2 front end with
rewrite and redirect turned on so I can authenticate via LDAP, use our
internal MySQL instead of the Zope DB, I want anyone to be able to edit
freely provided they have the right authentication credentials from our
organization, then import all the old knowledge base data from the Zope
2.5.1 install on the other Debian box to use in the new fresh install of
Zope on the new RHEL4 install.

Can anyone provide me some notes if you have similar installs and what I
need to do to get this up and running?  I have many projects going on
right now, this one, is just the tip of the iceberg of Open Source
technology that I am trying to absorb.  Please don't tell me to RTFM
because I am doing that already.  My head is literally spinning with
Perl, Python, LDAP, Apache, Zope, Linux, Unix, OpenBSD....Don't get me
wrong, I love it.  I just need to make some progress on this through a
good HowTO whether its already documented and I have overlooked it or if
any of you would like to spend some time to help a very receptive
learner.

Thank you for any assistance,

Tim
