Hello. Thank you for loading Zen Cart™.
You are seeing this page for one or more reasons:
1.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).


2.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 went into the includes/configure php file and did a edit thru my cp and did change the data base file name from my old database to the new one set up but it still gives me the same error. I hav only been on zen a few months. I did gt the handle on setting the original up with forum help. but I do not understand this. can someone direct me on what to do so I do not have to reload the store and start from scratch again.
