Okay, so i have  the following configuration:

Joomla! 2.5.8 Stable [ Ember ] 8-November-2012 14:00 GMT
Joomla Platform 11.4.0 Stable [ Brian Kernighan ] 03-Jan-2012 00:00 GMT
database Version 5.1.51-community-log
PHP Version 5.2.17
Web Server Apache
User Agent Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11

on VM2, i can create Manufacturers, Manufacturer categories, product categories and crate a product.

when i go to view the product on the front-end i get the following error message:

Server error
The website encountered an error while retrieving http://www.outrageousorangesky.com/index.php/products-for-sale/bath-and-skincare-products/hand-shovel-detail. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

this specific error is because i deleted my entries and installed the sample data.. but on my data i get the same error.  i even get the same error when i try to bring up the shopping cart or my account information.

so do i not have something set up correctly? or is there a misconfiguration?

i did a clean install of vm 2.0.16 and the aio ... and i would like to get my store front up soon so i can start to promote it.

thanks fo your help.

Quite often these are SEF problems, so turn off SEF and if you have a .htaccess file then rename it to htaccess.txt to disable it.

Have you looked at the server error log? There may be some indication there.
