500 Internal Server Error

I got the 500 Internal Server Error as in http://drupal.org/node/416906 on my site hosted at Site5.com. This was as soon as I went to install the site, even before anything else would appear.

I had to comment out the

# Set Memory limit to at least 128M either with the following line or in your server's php.ini.
# php_value memory_limit 128M

and put the

php_value memory_limit 128M

into my settings.php

then I could install.

I Hope this helps someone else.
