How to know OpenCart version

You can find out the version of your OpenCart store in several ways. Let’s go through them from the most accessible and fastest to the more complex ones.

Through the admin panel

1. Go to Admin → Home (Dashboard) or any other page.
2. Look at the bottom of the page, usually the OpenCart version is displayed there (for example, "OpenCart 3.0.3.9").

This data is taken from the admin panel localization files, and many OpenCart store developers often remove this information. In that case, you won’t find the version number at the bottom of the site.

How to know OpenCart version in the site code

1. Open the file index.php (in the site root) or admin/index.php.
2. At the beginning of these files, there is a constant with the version.

It looks like this:

// Version
define('VERSION', '3.0.3.7');

By the structure and style of the admin panel

If you don’t have access to the code, you can roughly determine the version by design and available functions:

• OpenCart 1.5 — old blue admin panel with a horizontal top menu.
• OpenCart 2.x — gray admin panel.
• OpenCart 3.x — similar to 2.x but with a gray-blue shade and with support for extensions via the official marketplace https://opencart.com. In the extensions section, you will find a link to this site.

And a bonus way to check your OpenCart version from our site

To find out which version your store is running, simply install our free extension. In the admin panel, in the right vertical menu, it will display the OpenCart version and PHP version, as well as show whether ionCube is installed, and if so, display its version.
