this page works fine at [url=http://listenlight.net/00/]http://listenlight.net/00/[/url]  but on my localhost (default ubuntu LAMP) it throws that error.  all the other pages work fine, and the code/markup is nearly identical.  thank you kindly for your time

Hi, it's a permission problem.

In the shell type the following commands
[code]chmod -R 777 /var/www
chown www-data:www-data /var/www[/code]
It should be /var/www if it's the LAMP from Ubuntu.

NOTE: You have to be root to use these functions there. If you a using Ubuntu you may prepend 'sudo'.
