Trisweb, if I just revist the setup page it again asks for user name and password.
.htaccess file is in /gallery :
Options -Indexes
DirectoryIndex admin.php
# Stop Ass Holes From Reading Private Files - Just In Case
# htaccess file for zenphoto
# NOTE: Change the RewriteBase below to the absolute path to your zenphoto directory.
<IfModule mod_rewrite.c>
RewriteEngine On
# !!! Change this to the web path (eg: http://www.example.com/photos --> /photos) !!!
RewriteBase /gallery
