This is your first time using Zen Cart® and you have not yet completed the normal installation procedures.
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).
This is not your first time using Zen Cart® and you have previously completed the normal installation procedures.
If this is the case for you, then...
Your /includes/configure.php and/or /admin/includes/configure.php files contain invalid path information and/or invalid database-connection information.
If you recently edited your configure.php files for any reason, or perhaps moved your site to a different folder or different server, then you will need to review and update all your settings to the correct values for your server.
Additionally, if the permissions have been changed on your configure.php files, then perhaps they are too low for the files to be read.
Or the configure.php files could be missing altogether.
Or your web hosting provider has recently changed the server's PHP configuration (or upgraded its version) then they may have broken things as well.
Additional *IMPORTANT* Details: includes/configure.php file empty or file not found, OR wrong DB_TYPE set, OR cannot find includes/autoload_func.php which suggests paths are wrong or files were not uploaded correctly
