Http 500 internal server error

[Ajeh]

Look at what you are using in the file:
/admin/includes/configure.php

for the:
DIR_FS_CATALOG

you should be using the same thing ...

Thanks, Ajeh

Well, I think that I'm at the end of my rope. Still getting a blank page when I try to access my catalog. Do you think that I will have to start over from the very beginning with a fresh installation?!!!

Do you think that I will have to start over from the very beginning with a fresh installation?

How much product data do you have?
Was/is this an upgrade or a fresh install?

[Ajeh]

What debug logs are being generated in the:
/cache

directory when you hit the blank page on your site?

Many thanks Ajeh and Kobra,

The tragedy for me is that I had just gotten the site to a point at which I felt comfotable enough to begin loading my products. I have "zero" programming skills, so getting to that point took weeks of siiting in front of the computer with the Zen Cart manual. And now it seems that all is lost!

The most recent error from my debug file is found below. What's strange is that the error is from 3/21. Nothing between 3/21 and today.

Kobra,

It was a fresh installation.

Do you have this line in your file, that is on the server, for:
/includes/configure.php

define('DIR_WS_TEMPLATES', DIR_WS_INCLUDES . 'templates/');

I recently installed zen cart 1.39H and experienced the same blank pages you describe. I can offer this. My 'work in progress - I'm migrating databases' store sits on a a shared server so I don't have access to apache root config files. However by adding a index directive to both the admin .htaccess file and adding the same directive to the store .htaccess file solved the problem for me. errors were of 500 internal server error type at the admin and at the store.

add on seperate line

DirectoryIndex index.php

Thanks Ajeh,

Yes. In my include/configure.php I have:

define('DIR_WS_TEMPLATES', DIR_WS_INCLUDES . 'templates/');

[Ajeh]

Could you post, from the server, without your password, the file:
/includes/configure.php
