Ok. I just upgraded Zen from 3.8 to 3.9 by:

a) diffing all files using total commander dir sync, and doing some more comparisons.
b) then went to /site/zc_install
c) went through the upgrade procedure which it did nicely there are no upgrade expections
d) the site shows fine
e) i renamed the admin dir
f) i edited the admin dir/includes/config and the main config made them 644

but when I go to the admin dir I get the

**"Hello. Thank you for loading Zen Cart™.

You are seeing this page for one or more reasons:

This is your first time using Zen Cart™ and you haven't yet completed the normal Installation procedure.
If this is the case for you, you will need to upload the "zc_install" folder using your FTP program, and then run zc_install/index.php via your browser (or reload this page to see a link to it).

Your /includes/configure.php and/or /admin/includes/configure.php file contains invalid path information and/or invalid database-connection information.
If you recently edited your configure.php files for any reason, or maybe moved your site to a different folder or different server, then you'll need to review and update all your settings to the correct values for your server.
See the Online FAQ and Tutorials area on the Zen Cart™ website for assistance.

I'm doing something stupid?

I'm pretty sure the config files are ok.

I'm pretty sure the config files are ok.
Not your admin configure if you are seeing that screen

Compare the front side DB details to those in the admin side

thanks! The line

"define('DIR_FS_CATALOG' missed one part in the physical path.

in the admin config.

It works. Great.

I definitely did something stupid. Kobra, you were right on. I found my mistake here:
the following path is a COMPLETE path to your Zen Cart files. eg: /var/www/vhost/accountname/public_html/store/

I didn't enter the COMPLETE path. Thank you.
