I started some work on a online store today that is using Zen Cart open source e-commerce software to power the store. I love Zen Cart, which initially was branched off of osCommerce, to power online stores and have used Zen Cart or osCommerce to power online stores for going on a decade. The first thing you should always do when beginning work on an already established site is get all of the information about the software(Zen Cart, osCommerce, WordPress, etc.) that runs the web site and the software used to power the site(MySQL, PostgreSQL, Apache, Litespeed, etc.). Zen Cart makes the initial task of obtaining information about the site and some of the server software fairly easy. Use the information below to obtain the Zen Cart version.
Find Out Version Of Zen Cart Software That Is Running:
First login to the Zen Cart admin which is typically located at http://www.somedomain.com/admin however many people change the /admin to something more complex like a random string of characters to make it harder for hackers to attack the Zen Cart administration area. You could either get the proper URL from the maintainer of the store or by poking around the Zen Cart directory on the server either using FTP or SSH. Once you have the correct URL open it in a browser and login to the Zen Cart admin section which will look similar to the below.
Zen Cart Administration Web Site:
Once the administration site is displayed similar to the above example image click Tools from the top navigation menu and select Server/Version info from the drop down as shown in the below image.
Zen Cart Admin Navigation: Tools Drop Down Menu
Once selected the Server/Version Info page will display. This informational page will display the Zen Cart version, PHP version, MySQL version, Apache Info, and much more data about the server such as PHP configuration settings as shown in the below example image.

That is it! You now have most of the basic information you should need to begin work on the Zen Cart online store you are working on.
