I am taking a class where we need to install the Zen Cart. I have completed all the requirements to download and install it. However I cannot view the admin page nor see the cart itself. I have attempted to troubleshoot using the basic instructions. What error message do I get? None. In FF which I will be using the page(s) are blank. However in IE it states a programming error a 500 error page. What do I do next? Should I uninstall and try again?
