Have you ever thought about making any changes in your OpenCart store, install new theme or modules?  If so, before starting to look for a module or a theme, you need to know the specifications of your own store in order to find the compatible extensions you may need.

Currently, there are 13 OpenCart versions available, since the first version OpenCart 1.5.4 released on August 16, 2012. Typically, OpenCart timeline is separated in two milestones, first one includes OpenCart 1.5.x versions starting from OpenCart 1.5.4 till, and the second milestone with versions from OpenCart till Between two major versions there is a big difference in the admin panel interface. Therefore, the OpenCart interface itself can help you distinguish between versions 1.5.x and 2.0.x.

OpenCart 1.5.x

Open this file and in the third line of code you will find the current OpenCart version used in your store.

// Version
define('VERSION', '');​
Now you can proceed with choosing the right modules and themes compatible with your OpenCart store version.

OpenCart 2.0.x
