Sounds like OU is unable to write to the file OOTPOU/setup.txt

I would check the permissions of the OOTPOU directory, and also OOTPOU/setup.txt and see if changing them allows OU to write to the file.

May also be worth creating a simple Perl script that writes to a file to see if maybe it is a server setup issue where cgi scripts do not have permission to write to the server.
