im using drupalcommerce version 7.x-2.11 on a pclinuxos 32 bit OS
Ive created settings.php

Used the following to make the settings.php file writeable and to allow the installer to edit the file:

chmod a+w sites/default/settings.php

changed file permissions using

chmod 666 settings.php

chmod a+w sites/default

and then tried to navigate to the drupalcommerce folder called kickstart
located in /var/www/html

with the url
localhost/kickstart

and gotten the following

The server encountered an internal error and was unable to complete your request. Error message:
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

has anyone else gotten this error? if so, have you heard of a solution for it?
