Here is a copy of my config-inc.php and header-inc.php files
http://www.offshoreonly.com/gallery/config-inc.php.txt http://www.offshoreonly.com/gallery/header-inc.php.txt
The only place i know to set the pp_path is in the admin GUI, where is the config file for that? It shows correctly in the GUI.
I did edit the pp-inc.php to fix the templates error message, by adding my path here.
// Little cleanup in case config-inc.php isn't current
if ( !defined('TMPL_PATH') ) {
define('TMPL_PATH', '/home/httpd/vhosts/offshoreonly.com/httpdocs/gallery/templates/');
}
