Error 500 on home page / Redirected to Admin Login

[trails202]

Fresh install of Zen Cart 1.3.8. New PHP, new MySQL. Insall works fine, Admin section works fine. Home page sometimes gives error 500 and sometimes redirects to admin/login.php if I'm already logged in as admin in another browser. Go to http://www.copperclassics.eu to see what I'm talking about...

Anybody got any clues? Thanks :)

Here's the configure.php:

Check if you have mixed up your Catalog and Admin configure.php files on the server ...

I go to your main domain name and it takes me to the Admin ...

The includes/configure/php and admin/includes/configure.php are in the right places.

I tried commenting out all the code in index.php and uncommenting the code line by line, then doing the same thing in any pages the code called into.

After getting a couple lines into the index and the template_top.php (or whatever the first file is) it became apparent that the execution of the code was completely arbitrary, and I was getting inconsistent results just by executing the same code a few times. Sometimes php would make it five lines in, sometimes two, sometimes one. It must be my server. The box I lease must have some residual configuration or other instability that kills the php process during execution.

Whatever the issue, I won't be able to run zen cart consistently on my server even though the admin and install routines seem to work fine. I guess I'll set it up on another hosting provider and manage it separately.

Thanks for the input. :) From what I've seen of zen cart on the test install on our development server it's pretty sweet.

The install on the alternate hosting seems to be running correctly.
