I haven't modified robot_functions.php, but here is my config.php file (with a .txt file extension):

http://search.napathon.net/includes/config.txt

You'll notice that I have some mods in it. I removed the database connection lgoic and made a separate file. Same thing with the admin username and password. Both files are in a directory that is not publicly accessible. Everything else should be pretty close to the "out of the box" version.

Hope this helps. :)

Thank You Very Much vinyl-junkie
i will compare it with my config file to see what different
